The acceptance of Islam by Hazrat Umar (R.A.) had great effect on the small amount of Muslims of Makkah, who were praying to Allah in secret. They now had the courage to preach Islam publicly.
The Quraish tried to bribe Rasulullah to give up Islam in exchange for gifts of wealth or any thing he would like. But our Prophet did not accept their bribe. The Quraish decided to torture and persecute even more.
Hazrat Bilal (R.A.), the slave of Umayya-bin-Khalaf, was laid flat on his back on hot sand. A hot heavy stone was placed on his chest and he was beaten while his hands were tied behind his back.
Hazrat Uthman (R.A.), a rich and prosperous man of the Banu Umayya tribe was tied up with ropes by his uncle and beaten and tortured.
Hazrat Ammar (R.A.), his father Hazrat Yaasir (R.A.) and his mother Sumayyah (R.A.) had embraced Islam. Abu Jahl killed Hazrat Sumayya (R.A.) with a sharp spear.
Abu Jahl also beat slave lady Hazrat Zaeerah (R.A.) in such a way that she became totally blind.
Some helpless Muslims like Hazrat Khabbab-bin-Aett (R.A.) were pushed into a fire.
