Wiping over the leather socks

Sayyiduna Bilal (may Allah be pleased with him) narrates: I went with the Messenger of Allah (peace and blessings be upon him) into "al-Aswaf" (a garden of Madinah). He (peace and blessings be upon him) went to relieve himself, then when he came back I offered him (peace and blessings be upon him) water, and he (peace and blessings be upon him) performed ablution. Then he (peace and blessings be upon him) tried to bring out both his forearms through the neck opening of his shirt, but they would not come out (because it was tight), so he (peace and blessings be upon him) brought them out from beneath the cloak. Then he (peace and blessings be upon him) completed the ablution and wiped over his leather socks.
This hadith is sahih (authentic) from the narration of Imam Malik bin Anas, and it is also sahih on the condition of Imam Bukhari and Imam Muslim, but the two Shaykhs did not record it. There is a great benefit in it: the two Shaykhs did not record the hadith of Safwan bin Assal about wiping over leather socks when resident and the fixing of its time limit; rather, they agreed on the narrations of Sayyiduna Ali and Mughirah bin Shu'bah. And "al-Aswaf" is one of the well-known quarters of Madinah.

Sayyiduna Usamah bin Zayd (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) entered "al-Aswaf" and went to relieve himself, and Sayyiduna Bilal (may Allah be pleased with him) was with him. When they came out, I asked Bilal (may Allah be pleased with him): What did he (peace and blessings be upon him) do? He said: "He (peace and blessings be upon him) performed ablution: he washed his face and his hands, wiped his head, and also wiped over his leather socks."
This hadith is sahih (authentic) on the condition of Imam Muslim, because he used Dawud bin Qays as evidence.

Sayyiduna Abdullah bin Zayd al-Ansari (may Allah be pleased with him) narrates: I saw the Messenger of Allah (peace and blessings be upon him) performing ablution. He (peace and blessings be upon him) took separate water for (wiping) his ears, other than the water with which he (peace and blessings be upon him) had wiped his head.
This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, if it is free of (any weakness from) this Ibn Abi Ubaydillah, for both of them used all of its narrators as evidence.

It is narrated from Sayyiduna Abdullah bin Zayd (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) wiped his ears with water other than the water with which he had wiped his head. This narration clarifies the meaning of the first narration, and it is sahih (authentic) like it.

It is narrated from Sayyidah Rubayyi' bint Mu'awwidh (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) wiped the inner and outer parts of his ears.
Although the two Shaykhs (Bukhari and Muslim) did not use Ibn Aqil as evidence, his hadith is sound and acceptable.
