Prophet Muhammad faced many hardships while he was calling its inhabitants to Islam, the chiefs in this town did many shameful acts against the prophet and his companions, let me numerate some of these shameful acts:

• In Mekka, the prophet was ridiculed and persecuted.
• In Mekka his companions were enforced to emigrate leaving their wealth and many of his followers were killed.
•  In Mekka, they planned to kill the prophet.
• In Mekka, he was economically and socially boycotted for three years till children screamed out of hunger.
• In Mekka, all wars were planned against the prophet after he emigrated to Madina.
•  In Mekka, the worst slanders against the prophet were weaved, they propagated that he was a mad, a magician and an imposter.
• In Mekka, the chief masters worked in cahoots with the Jews to abort the Islamic call by all possible means.

From Mekka most of the major wars against the prophet were launched against the Islamic call in Madina.
Never were the hostile activities stopped against the Islamic state even when truce and military acts was suspended. Upon the infringement of the pact held between the prophet and the leaders of the enemy, the prophet decided to conquer Mekka.

 What do you expect the prophet should do?

There the Mekkans stood waiting what he would do with them, they were all waiting themselves to be smitten.
The prophet asked them" what do you think I would do with you?"

"You are a generous brother and the son of a generous brother."

They answered.
The prophet then said:

                Go. You are free.

 In a moment  the prophet suppressed all the pains they inflicted on him and forgave them all.
If the prophet had smitten those enemies who worked day and night to undermine the Islamic state, he wouldn't have been blamed.
 Among those who were standing before the prophet and he forgave them were:
Abu Sufyan, a Quraysh leader  who led the armies against Islam and enticed tribes against Islam

 Ikrimah ibn Abu Jahl, an enemy whose father was one of the Prophet's  evil enemies that several time tried to humiliate the prophet and was the one who always planned against Islam.

Hind, the wife of Abu Sufyan, who ripped open the corpse of the Prophet's beloved uncle Hamza after the Battle of Uhud and ripped out his heart and liver and ate it.
Wahshi, the man sent by Hind to murder Hamza;
 Utbah, the son of another of the Prophet's greatest foes, Abu Lahab, who had divorced the Prophet's daughter Ruqayyah under pressure from his father.
