Sunan Abu Dawood 442
Anas b. Malik reported the Prophet ﷺ as saying:
If any one forgets a prayer or oversleeps, he should observe it when he remembers it ; there is no expiation for it except that.
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ النَّبِيَّ ﷺ قَالَ
" مَنْ نَسِيَ صَلاَةً فَلْيُصَلِّهَا إِذَا ذَكَرَهَا لاَ كَفَّارَةَ لَهَا إِلاَّ ذَلِكَ " .
