Sunan Abi Dawud, Hadith 3760 ⓘ

Narrated Abdullah ibn Abbas: The Messenger of Allah came out from the privy and was presented to him. They (the people) asked: Should we bring you water for ablution? He replied: I have been commanded to perform ablution when I get up for prayer.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنَا أَيُّوبُ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي مُلَيْكَةَ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم خَرَجَ مِنَ الْخَلاَءِ فَقُدِّمَ إِلَيْهِ طَعَامٌ فَقَالُوا أَلاَ نَأْتِيكَ بِوَضُوءٍ فَقَالَ ‏ "‏ إِنَّمَا أُمِرْتُ بِالْوُضُوءِ إِذَا قُمْتُ إِلَى الصَّلاَةِ ‏" ‏ ‏.‏
