Ibn ‘Abbas told that when food was presented to the Prophet (ﷺ) or, his coming out from the privy and he was asked whether they should bring him water for ablution, he replied, “I have been commanded to perform ablution only when I get up for prayer.” Tirmidhi, Abu Dawud and Nasa’i transmitted it, and Ibn Majah transmitted it on Abu Huraira’s authority.

وَعَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ مِنَ الْخَلَاءِ فَقُدِّمَ إِلَيْهِ طَعَامٌ فَقَالُوا: أَلَا نَأْتِيكَ بِوَضُوءٍ؟ قَالَ: «إِنَّمَا أُمِرْتُ بِالْوُضُوءِ إِذَا قُمْتُ إِلَى الصَّلَاةِ» . رَوَاهُ التِّرْمِذِيّ وَأَبُو دَاوُد وَالنَّسَائِيّ وَرَوَاهُ ابْن مَاجَه عَن أبي هُرَيْرَة
