when he was delayed (1). This constituted his approval of their appointing ‘Abd al-Rahmān to lead them.
Whenever he travelled away from Medina, he appointed someone to lead the Muslims in prayer in his place. On some occasions he appointed Ibn Umm Maktūm, on another he appointed ‘Alī, and on others he appointed someone else.
As for his absence and illness (2), he appointed only Abū Bakr—not ‘Alī or anyone else. His appointment of al-Siddīq (the Truthful) to lead the prayer is established by mass transmission and recorded through multiple chains in the collections of authentic hadith, the Sunan, and the Musnads. Al-Bukhārī, Muslim, Ibn Khuzaymah, Ibn Hibbān, and other compilers of authentic hadith narrated from Abū Mūsā al-Ash‘arī, who said:
“The Prophet, may Allah bless him and grant him peace, fell ill, and his illness became severe. He said, ‘Tell Abū Bakr to lead the people in prayer.’ ‘Ā’ishah said, ‘O Messenger of Allah, Abū Bakr is a tender-hearted man. Whenever he stands in your place, he will be unable to lead the people in prayer.’ He said, ‘Tell Abū Bakr to lead the people in prayer, for you women are like the women around Joseph.’ So Abū Bakr led them in prayer during the lifetime of the Messenger of Allah, may Allah bless him and grant him peace.”
Al-Bukhārī (3) mentioned in this report that ‘Ā’ishah urged the Prophet, may Allah bless him and grant him peace, to reconsider three times (4).
