Narrated Ibn Abu Habib:
Abu Al-Khair said, "As-Sanabih, I asked (me), 'When did you migrate?' I (i.e. Abu Al-Khair) said, 'We went out from Yemen as emigrants and arrived at Al-Juhfa, and there came a rider whom I asked about the news. The rider said: We buried the Prophet (ﷺ) five days ago." I asked (As-Sanabihi), 'Did you hear anything about the night of Qadr?' He replied, 'Bilal, the Mu'adh-dhin of the Prophet (ﷺ) informed me that it is on one of the seven nights of the last ten days (of Ramadan).
