Zayd bin al-Habab al-'Akli زيد بن الحباب أبو الحسين العكلي · The Book of the Prayer

"The Messenger of Allah said: 'My Ummah will continue to adhere to the Fitrah so long as they do not delay the Maghrib until the stars have come out." (Hasan)Abu 'Abdullah bin Majah said: I heard Muhammed bin Yahya saying: 'The people in Baghdad were confused in narrating this Hadith. Abu Bakr Al-A'yan and I went to 'Awwam bin 'Abbad bin 'Awwam and he brought out to us the book of his father, and this Hadith was in it.'"

'The Prophet was asked about a man who forgets prayer or sleeps and misses it. He said: 'he performs it when he remembers it.'"
