It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever does not perform witr has no prayer." This reached the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), and she said: "Who heard this from Abu al-Qasim (peace and blessings be upon him)? By Allah, neither has much time passed nor have I forgotten. What Abu al-Qasim (peace and blessings be upon him) said was: 'Whoever comes on the Day of Resurrection with the five prayers, having fully guarded their ablution, their times, their bowing and their prostrations, and having diminished nothing of them, will come with a covenant from Allah that He will not punish him. And whoever comes having diminished something of them has no covenant with Allah; if He wills He will have mercy on him, and if He wills He will punish him.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these two hadiths from Muhammad except Isa, and Abdullah is alone in narrating both of them."
