When the Quraish noticed that an open invitation was being given to Islam and idolatry was being openly condemned and criticized, they could not tolerate this. They thus prepared to show enmity and hostility to the one who invited to One Allah, and they prepared to oppose tauheed (proclaiming the oneness of Allah Ta‘ala). They resolved to cause such harm and pain to Rasulullah (sallallahu ‘alaihi wasallam) that he would be dissuaded and refrain from inviting people towards Islam.
