Imam al-Hakim says: I heard Abu al-Abbas Muhammad bin Ya'qub say: I heard al-Abbas bin Muhammad al-Duri say that Yahya bin Ma'in used to say: Ata' bin Yasar narrated from Abdullah al-Sunabihi, a Companion, who is also called Abu Abdullah. Bear in mind that al-Sunabihi (Abd al-Rahman bin Usaylah) is the associate of Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him), while another al-Sunabihi (al-Sunabih bin al-A'sar) is the associate of Qays bin Abi Hazim.

It is narrated from Sayyiduna Thawban (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Remain steadfast in the religion (adopt istiqamah), though you will not be able to encompass all deeds fully (or fulfil their due); and know that among your best deeds is prayer, and none keeps up ablution except a believer."

It is narrated from Sayyiduna Thawban (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Stay on the straight path, and you will not be able to count all good deeds; and know that the best of your deeds is prayer, and none guards his ablution except a believer." In this narration, Mansur bin al-Mu'tamir corroborated al-A'mash.

It is narrated from Sayyiduna Thawban (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Adopt steadfastness, and you will not be able to encompass it fully; and know that the best of your deeds is prayer, and none persists in ablution except a believer." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. I do not know of any defect in it that would weaken it, except an error (wahm) by Abu Bilal al-Ash'ari that he made in narrating it from Abu Mu'awiyah.

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Be steadfast; you will not be able to count it; and know that among your best deeds is prayer, and none persists in ablution except a believer."

It is narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever performs ablution and performs it in the best manner, then prays two rak'ahs without letting any (worldly) thought into them (praying them with full attention), his past sins are forgiven."

It is narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) that whoever performs ablution well and prays two rak'ahs in which there is no heedlessness (sahw), his previous sins are forgiven. This hadith is sahih (authentic) on the condition of Imam Muslim; there is no defect in it that would weaken it, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever performs ablution and performs it well, then prays two rak'ahs in such a state that he does not wander (into any worldly matter) in them, his past sins are forgiven." Imam al-Hakim says that this is an error (wahm) of Muhammad bin Aban, because he is a weak narrator, whereas Muslim used Hisham bin Sa'd as evidence (whose narration has already passed at number 456).

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.
