First man to accept Islam
Hadrat Abu Bakr was a firm friend of the Holy Prophet and knew him better than any other man. His honesty, nobility, truthfulness and trustworthiness, had great attraction for Abu Bakr.

In this way he was the first adult free man to believe in the Holy Prophet's Mission, and became his confidant. The Holy Prophet (Sallallahu 'alaihi wa Sallam) once spoke about this, "When I invited people towards Allah, everybody thought over it and hesitated, at least for a while, except Abu Bakr who accepted my call the moment I put it before him, and he did not hesitate even for a moment." When he accepted Islam, the Holy Prophet (Sallallahu 'alaihi wa Sallam) was very pleased. Da'wat (Invitation) towards Allah
As soon as he had accepted Islam he started the work of Da'wat (Invitation towards Allah) first secretly and then openly when it was so allowed by the Holy Prophet (Sallallahu 'alaihi wa Sallam). First he went to ‘Uthman, Talha, Zubair and Said (Ridwanullah 'alaihim 'Ajma'in).
