Ati reported that he saw Uthman call for a vessel of water. Uthman poured water over his hands three times and washed them, then dipped his right hand into the vessel, rinsed his mouth, and cleaned his nose. He then washed his face three times, washed his arms up to the elbows three times, wiped his head, and washed his feet three times.Then he said, "The Messenger of Allah ﷺ said, 'Whoever performs ablution as I have just done, then prays two units of prayer without letting his mind wander during them, his past sins will be forgiven.'"
و حدثني زهير بن حرب حدثنا يعقوب بن إبراهيم حدثنا أبي عن ابن شهاب عن عطاء بن يزيد الليثي
أنه رأى عثمان دعا بإناء فأفرغ على كفيه ثلاث مرار فغسلهما ثم أدخل يمينه في الإناء فمضمض واستنثر ثم غسل وجهه ثلاث مرات ويديه إلى المرفقين ثلاث مرات ثم مسح برأسه ثم غسل رجليه ثلاث مرات ثم قال قال رسول الله ﷺ من توضأ نحو وضوئي هذا ثم صلى ركعتين لا يحدث فيهما نفسه غفر له ما تقدم من ذنبه
