'Aishah (May Allah be pleased with her) said:
With the start of the last ten days of Ramadan, Messenger of Allah ﷺ would pray all the night, and would keep his family awake for the prayers. He tied his lower garment (i.e., avoided sleeping with his wives) and devoted himself entirely to prayer and supplication.

[Al-Bukhari and Muslim].

الخامس: عن عائشة رضي الله عنها أنها قالت: " كان رسول الله ﷺ إذا دخل العشر أحيا الليل، وأيقظ أهله، وجد وشد المئزر" ((متفق عليه)).
