The virtue of the prayer after wudu

It is narrated from Sayyiduna Amr bin Abasah (may Allah be pleased with him) that Abu Ubayd said to him: "Narrate to us a hadith that you heard from the Messenger of Allah (peace and blessings be upon him)." He said: I heard the Messenger of Allah (peace and blessings be upon him) not once, not twice, but more than three times, saying: "When a believing servant performs ablution, rinses his mouth and cleans his nose, the sins fall away from the edges of his mouth; when he washes his hands, the sins fall away from his nails; when he wipes his head, the sins fall away from the edges of his head; then if he stands and prays two rak'ahs, keeping his heart and his gaze fully turned towards Allah, he comes out of his sins as pure as if his mother had given birth to him that very day."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. Abu Ubayd is an early Tabi'i whose hearing from Amr bin Abasah is established.

It is narrated that Shurahbil bin Hasanah said: "Who will narrate to us from the Messenger of Allah (peace and blessings be upon him)?" Sayyiduna Amr bin Abasah (may Allah be pleased with him) said: "I will. I heard the Messenger of Allah (peace and blessings be upon him) not once and not twice, but five times (on different occasions), say: 'When a Muslim brings his ablution water near and washes his palms, his sins leave from between his fingers and from his fingertips; when he washes his face, the sins leave from the edges of his beard; when he wipes his head, the sins leave from the ends of his hair; and when he washes his feet, the sins leave from the soles of his feet.'"
It has a supporting narration (shahid) on the condition of Imam Muslim, also from Amr bin Abasah.

It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Performing ablution fully in disagreeable conditions (such as cold or illness), walking to the mosques, and waiting for the next prayer after a prayer wash away sins just as water washes away dirt."
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
