Riyad as-Saliheen 1408
Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "There are two statements that are light for the tongue to remember, heavy in the Scales and are dear to the Merciful: 'Subhan-Allahi wa bihamdihi, Subhan-Allahil-Azim [Glory be to Allah and His is the praise, (and) Allah, the Greatest is free from imperfection]'."
[Al-Bukhari and Muslim].
وعن أبي هريرة رضي الله عنه قال: قال رسول الله ﷺ:
"كلمتان خفيفتان على اللسان، ثقيلتان في الميزان، حبيبتان إلى الرحمن: سبحان الله وبحمده، سبحان الله العظيم" ((متفق عليه)).
