Hadith 8:171
'Ali (May Allah be pleased with him) reported:
The Prophet (ﷺ) visited me and Fatimah (May Allah be pleased with her) one night and said, "Do you not observe prayer (at night)?" [Al-Bukhari and Muslim] .
وعن علي رضي الله عنه، أن النبي صلى الله عليه وسلم، طرقه وفاطمة ليلا، فقال: "ألا تصليان؟" ((متفق عليه))
