Sunan Abi Dawud, Book 2, Hadith 447 (USC-MSA) ⓘ
Narrated Abdullah ibn Mas'ud: We proceeded with the Messenger of Allah on the occasion of al-Hudaybiyyah. The Messenger of Allah said: Who will keep watch for us? Bilal said: I (shall do). The overslept till the sun arose. The Prophet awoke and said: Do as you used to do (i.e. offer prayer as usual). Then we did accordingly. He said: Anyone who oversleeps or forgets (prayer) should do similarly.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ جَامِعِ بْنِ شَدَّادٍ، سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ أَبِي عَلْقَمَةَ، سَمِعْتُ عَبْدَ اللَّهِ بْنَ مَسْعُودٍ، قَالَ أَقْبَلْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم زَمَنَ الْحُدَيْبِيَةِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ يَكْلَؤُنَا " . فَقَالَ بِلاَلٌ أَنَا . فَنَامُوا حَتَّى طَلَعَتِ الشَّمْسُ فَاسْتَيْقَظَ النَّبِيُّ صلى الله عليه وسلم فَقَالَ " افْعَلُوا كَمَا كُنْتُمْ تَفْعَلُونَ " . قَالَ فَفَعَلْنَا . قَالَ " فَكَذَلِكَ فَافْعَلُوا لِمَنْ نَامَ أَوْ نَسِيَ " .
