حَدَّثَنَا إِسْمَاعِيلُ أَنْبَأَنَا أَيُّوبُ عَنِ ابْنِ أَبِي مُلَيْكَةَ عَنِ ابْنِ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ مِنْ الْخَلَاءِ فَقُرِّبَ إِلَيْهِ طَعَامٌ فَعَرَضُوا عَلَيْهِ الْوَضُوءَ فَقَالَ إِنَّمَا أُمِرْتُ بِالْوُضُوءِ إِذَا قُمْتُ إِلَى الصَّلَاةِ
مسند امام احمد بن حنبل · Hadith 3381
It was narrated from Ibn 'Abbas (RA) that the Messenger of Allah (PBUH) came out of the out- house and food was brought to him and water for zvudoo' was offered to him, but he said: "I have only been commanded to do wudoo’ when i get up to pray."
