Jundub bin Sufyan (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "He who offers the dawn (Fajr) prayers will come under the Protection of Allah. O son of Adam! Beware, lest Allah should call you to account in any respect from (for withdrawing) His Protection."

[Muslim].

وعن جندب بن سفيان رضي الله عنه قال: قال رسول الله ﷺ:
"من صلى الصبح فهو في ذمة الله فانظر يابن آدم، لا يطلبنك الله من ذمته بشيء". ((رواه مسلم)).
