'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 ﷺ يصبح جنبًا من غير حلم ثم يصوم. ((متفق عليه))
