Sunan Ibn Majah 696
The Book of the Prayer
Whoever Sleeps Through Prayer Or Forgets it
حَدَّثَنَا جُبَارَةُ بْنُ الْمُغَلِّسِ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ مَنْ نَسِيَ صَلاَةً فَلْيُصَلِّهَا إِذَا ذَكَرَهَا .
It was narrated that Anas bin Malik said: "The Messenger of Allah said: 'Whoever forgets a prayer, let him perform it when he remembers it.'"
