Prayer at Night (Tahajjud)
Chapter: Leaving the night prayer by a patient
Narrated Jundab bin `Abdullah:
Gabriel did not come to the Prophet (for some time) and so one of the Quraish women said, "His Satan has deserted him." So came the Divine Revelation: "By the forenoon And by the night When it is still! Your Lord (O Muhammad) has neither Forsaken you Nor hated you." (93.1-3)
