As long as Rasulullah (sallallahu ‘alaihi wasallam) sufficed on inviting the people to Islam, the Quraish did not interfere with him. However, when he began to invite to Islam openly, began to speak ill of the idol worshippers and began to prevent people from engaging in kufr and shirk, the Quraish began to show him enmity and oppose him. However, Abu Taalib continued to support and assist Rasulullah (sallallahu ‘alaihi wasallam).
