حَدَّثَنَا عَفَّانُ حَدَّثَنَا وُهَيْبٌ حَدَّثَنَا أَيُّوبُ عَنِ ابْنِ أَبِي مُلَيْكَةَ عَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ مِنْ الْخَلَاءِ فَأُتِيَ بِطَعَامٍ فَقِيلَ لَهُ أَلَا تَتَوَضَّأُ فَقَالَ إِنَّمَا أُمِرْتُ بِالْوُضُوءِ إِذَا قُمْتُ إِلَى الصَّلَاةِ
مسند امام احمد بن حنبل · Hadith 2549
It was narrated from Ibn 'Abbas (RA) that the Prophet (PBUH) came out of the outhouse and some food was brought. It was said to him: Aren't you going to do wudoo '? He said: "I have only been commanded to do zoudoo when I get up to pray."
