Silsilah as-Sahihah 498 — Allah guarantees the one who prays Fajr

It is narrated from Sayyiduna Jundub Qasri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever performs the morning prayer is under the protection of Allah, (so O man! consider carefully) let it not be that Allah questions you regarding His guarantee, and whoever Allah questions regarding His guarantee, He will seize him and throw him face down into Hell."
