Hadith 8:255
'Aishah, and Umm Salamah (May Allah be pleased with them) reported:
The Messenger of Allah (ﷺ) would wake during Ramadan (fasting) in a state of major impurity without a wet dream, but on account of sexual intercourse and he would take a bath before dawn. [Al- Bukhari and Muslim] .
وعن عائشة وأم سلمة رضي الله عنهما قالتا: كان رسول الله صلى الله عليه وسلم يصبح جنبًا من غير حلم ثم يصوم. ((متفق عليه))
