وعن أبي هريرة رضي الله عنه، عن النبي صلى الله عليه وسلم قال‏:‏ ‏"‏من قام ليلة القدر إيمانا واحتسابًا غفر له ما تقدم من ذنبه‏"‏‏.‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏ ‏.‏

'Aishah (May Allah be pleased with her) reported

The Messenger of Allah (ﷺ) used to seclude himself (in the mosque) during the last ten nights of Ramadan. He would say, "Search for Lailat-ul-Qadr (Night of Decree) in the last ten nights of Ramadan."[Al-Bukhari and Muslim].
