Prophets
Chapter: The Statement of Allah Taa'la: "Verily, in Yusuf and his brethren there were Ayat..."
Narrated `Aisha:
That the Prophet (ﷺ) said (to her). "Order Abu Bakr to lead the people in prayer." She replied," Abu Bakr is a soft-hearted person and when he stands at your place, he will weep (so he will not be able to lead the prayer)." The Prophet (ﷺ) repeated the same order and she gave the same reply. The narrator, Shuba said that the Prophet (ﷺ) said on the third or fourth time. "You are (like) the female companions of Joseph. Order Abu Bakr to lead the prayer. "
