Silsilat al-Ahadith al-Sahihah

It is narrated from Abu Tamim Jaishani that Sayyiduna Amr bin Al-As (may Allah be pleased with him) delivered a sermon to the people on Friday and said: Abu Basrah has informed me that the Noble Prophet (peace and blessings of Allah be upon him) said: “Allah Almighty has granted you an additional prayer, which is Witr. Perform this prayer in the interval between the Isha prayer and the Fajr prayer.” Abu Tamim said: Sayyiduna Abu Dharr (may Allah be pleased with him) took my hand and went to Abu Basrah (when he reached him, he) asked: Did you hear from the Messenger of Allah (peace and blessings of Allah be upon him) the hadith that Amr has narrated? Abu Basrah said: (Yes) I heard this hadith from the Messenger of Allah (peace and blessings of Allah be upon him).
