Mercy to all mankind:

Hadrat Abu Huraira (may Allah be pleased with him) said: the Prophet (may Allah’s blessings and peace be upon him) was asked to curse the infidels. He said, “I have not been sent to curse people but as a mercy to all mankind.” (Muslim)

Mother of faithful believers Hadrat Aisha (may Allah be pleased with her) said that she once asked the Holy Prophet (may Allah’s blessings and peace be upon him): ‘Did you face a day severer than the day of the battle of Uhud? ‘He answered:

‘Yes I have experienced such things at the hands of your people and such a day was the day of Aqabah. On this day I presented myself to Abdi lail bin Abd Kulal and offered him Islam, but he failed to make any responce to what I had offered to him. I therefore, left with a heavy heart and depressed.

I felt some relieft only when I reached Qarn Sa’alib. Here I looked up and saw a cloud covering me. In this cloud I saw Angel Jibril (peace be upon him) who called me and said: Allah, the Most High, has heard what your people have said to you and the response to your offer. Allah has now sent the Angel of the Mountains to you to carry out your orders to do what you might like to be done to them.

Then the Angel of the Mountains addressed me greeting with Salam and then said: ‘Muhammad! Allah (The Glorified and the Exalted) has heard what your people have said to you. I am the Angel of the Mountains and my Lord has sent me to you to carry out your orders. What do you want now to be done?

If you like I may crush them between the two mountains encircling the city of Makka. The Holy Prophet (may Allah’s blessings and peace be upon him) replied: (I do not want their destruction) I am still hopeful that Allah will make some of their children (good Muslims) who would worship Allah, the One, without associating anybody with Him. (Bukhari and Muslim).

His forgiveness:

Hadrat Anas (may Allah be pleased with him) reported that a Jew came to Allah’s Messenger (may Allah’s blessings and peace be upon him) with poisoned mutton and he took of what had been brought to him. (When the effect of his poison were felt by him) he called for her and asked her about that, whereupon she said: I had determined to kill you. Thereupon he said:

Allah will never give you the power to do it. He (the narrator) said that they (the Companions of the Holy Prophet) said: Should we not kill her? Thereupon he said: No. He (Anas) said: I felt (the effects of this poison) on the uvula of Allah’s Messenger. (Muslim)

It has been narrated on the authority of Hadrat Anas bin Malik (may Allah be pleased with him) that eighty persons from the inhabitants of Makka swooped down upon Allah’s Messenger (may Allah’s blessings and peace be upon him) from the mountain of Tan’im.

They were armed and wanted to attack the Holy Prophet (may Allah’s blessings and peace be upon him) and his Companions unawares. He (the Holy Prophet) captured them but spared their lives. So, Allah (The Glorified and the Exalted) revealed the verse: “And It is He Who restrained your hands from them and their hands from you in the valley of Makkah after He had given you a victory over them.” (48:24) (Muslim)

He fought only for Allah (The Glorified and the Exalted/ For Blashmious):

Mother of faithful believers, Hadrat Aisha (may Allah be pleased with her) said that the Holy Prophet (may Allah’s blessings and peace be upon him) never struck anybody with his hand, neither a servant nor a women, but he did fight (jihad) in the cause of Allah. He never avenged any wrong done to him personally, but he did avenge a wrong violating divine commandments. (Muslim)

Some Non-Muslims are narrow-minded and would think that it was a ruel act Prophet did?
Its not, Even Bible says to kill the blashmious as God doesn’t like this Bible says:

Leviticus 24:10-16 NLT:
“One day a man who had an Israelite mother and an Egyptian father got into a fight with one of the Israelite men. During the fight, this son of an Israelite woman blasphemed the LORD’s name. So the man was brought to Moses for judgment. His mother’s name was Shelomith. She was the daughter of Dibri of the tribe of Dan. They put the man in custody until the LORD’s will in the matter should become clear.

Then the LORD said to Moses, “Take the blasphemer outside the camp, and tell all those who heard him to lay their hands on his head. Then let the entire community stone him to death. Say to the people of Israel: Those who blaspheme God will suffer the consequences of their guilt and be punished.

Anyone who blasphemes the LORD’s name must be stoned to death by the whole community of Israel. Any Israelite or foreigner among you who blasphemes the LORD’s name will surely die”

His concern for the people:

Hadrat Abu Qatadah Haris Ibn Rib’i (may Allah be pleased with him) relates that the Holy Prophet (may Allah’s blessings and peace be upon him) said: I stand up for Prayer [Salat] intending to prolong it. In the meantime I hear the wailing of a baby and I have to shorten my prayer, being apprehensive lest my recitation of a long verse may tell upon the baby’s mother. (Bukhari)

Honesty, Trustworthiness and Reliability:

The Prophet (pbuh) was wellknown for his honesty. The pagans of Makkah -who were openly hostile towards him- would leave their valuables with him. His honesty and reliability was tested when the pagans of Makkah abused him and tortured his companions and drove them out of their homes. He ordered his cousin, Ali b. Abi Talib to postpone his migration for three days to return to people their valuables.

Another example of his honesty, trustworthiness and reliability is demonstrated in the Truce of Hudaibiyah, wherein he agreed to the article in the treaty which stated that any man who left the Prophet (pbuh) would not be returned to him, and any man who left Makkah would be returned to them.

Before the treaty was concluded a man named Abu Jandal b. Amr had managed to escape from the pagans of Makkah and rushed to join Muhammad (pbuh). The pagans asked Muhammad to honor his pledge and return the escapee. The Messenger of God (pbuh) said:

“O Abu Jandal! Be patient and ask God to grant you patience. God will surely help you and those who are persecuted and make it easy for you. We have signed an agreement with them, and we certainly do not betray or act treacherously.” (Baihaquee #18611)

He did not speak to please but always said the truth:

Hadrat ‘Amr ibn al-Aas (may Allah be pleased with him) reports that the Holy Prophet (may Allah’s blessings and peace be upon him) in his special talk, used to pay attention even to the worst man in the community with a view to win his heart. “Towards me also,” states Hadrat ‘Amr (may Allah be pleased with him), “he used to pay much attention, addressing me more than he did others, wherefore I began to think that I was the best man in the community.

So under this impression, one day I asked him: “Am I superior or Hadrat Umar?” He said, ‘Umar’. Again I asked him clearly, he told me correctly, without fear or favour, and later on I thought I should not have asked him such things.” (Tirmidhi)

Cooperation:

The Prophet (pbuh) was not a king who commanded his followers to carry out his orders. Rather he always carried out his own affairs and helped others in collective duties. A’ishah was once asked about how the Prophet (pbuh) behaved with his family. She said:
“He helped and assisted his family members with their chores; but when the call to prayer was heard, he would [stop everything and] leave to attend the prayers.”

Al-Baraa bin ‘Azib said:
“I saw the Messenger of God (pbuh) on the Day of the Trench carrying dirt [that was dug from the trench] until his chest was covered with dirt.” (Bukhari #2780)

Truthfulness:

A’ishah said:
“The trait and characteristic which the Prophet (pbuh) hated most was lying. A man would tell a lie in the presence of the Prophet (pbuh) and he would hold it against him, until he knew that he repented.” (Tirmidthi #1973)

Even his enemies attested to his truthfulness. Abu Jahl, who was one of the harshest enemies of Islam, said: ‘O Muhammad! I do not say that you are a liar! I only deny what you brought and what you call people to.’ God, the Exalted, says:
“We know indeed that what they say certainly grieves you, but surely they do not call you a liar; but the unjust deny the verses of God.” [6:33]

Justice and Fairness:

‘The people of Quraish were extremely concerned about a Makhzoomi woman (i.e. the woman from the tribe of Makhzoom) who committed a theft. They conversed among themselves and said, ‘Who can intercede on her behalf with the Messenger of God (pbuh)?’

They finally said: ‘Who dares to speak to the Messenger of God (pbuh) in this matter except Usamah b. Zaid, the most beloved young man to the Messenger of God (pbuh).’ So Usamah spoke to the Messenger of God (pbuh) regarding the woman. The Messenger of God (pbuh) said:

‘O Usamah! Do you intercede (on their behalf to disregard) one of God’s castigations and punishments!’
The Messenger of God (pbuh) got up and delivered a speech, saying:

‘People before you were destroyed because when the noble among them stole, they would let him go; and if the poor and weak stole they would punish him. By God! If Fatimah, the daughter of Muhammad stole, I would cut her hand off.’ (Bukhari #3288)

The Messenger of God (pbuh) was just and fair and allowed others to avenge themselves if he harmed them. Usaid b. Hudhair said:
‘A man from the Ansar, was cracking jokes with people and making them laugh, and the Prophet (pbuh) passed by him and poked his side lightly with a branch of a tree that he was carrying. The man exclaimed: ‘O Prophet of God! Allow me to avenge myself!’ The Prophet (pbuh) said: ‘Go Ahead!’

The man said: ‘O Messenger of God, you are wearing a garment, and I was not when you poked me [i.e. you jabbed my exposed skin, so it is only fair I do the same to you]!’ The Messenger of God (pbuh) raised his upper garment [to expose his side], and the Ansari [merely] kissed it, saying: ‘I only meant to do this, O Messenger of God!’ (Abu Dawood #5224)

And There are more qualities of him..
