The command to perform wudu thoroughly, pass water between the fingers and sniff water deeply into the nose

Asim bin Laqit bin Sabirah narrates from his father, who was the delegate of Banu al-Muntafiq, that he and a companion of his came to Sayyidah Aishah (may Allah be pleased with her) looking for the Messenger of Allah (peace and blessings be upon him), but he (peace and blessings be upon him) was not there. Sayyidah Aishah (may Allah be pleased with her) fed them dates and porridge. Only a short while had passed when the Messenger of Allah (peace and blessings be upon him) arrived with a dignified gait. He (peace and blessings be upon him) asked: "Has anyone given you food?" I said: Yes, O Messenger of Allah. Then I said: O Messenger of Allah, tell us about the prayer. He (peace and blessings be upon him) said: "Perform ablution thoroughly, pass (water) between the fingers, and sniff water into the nose thoroughly, unless you are fasting."

It is narrated from Sayyiduna Laqit bin Sabirah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When you sniff water into your nose, do so thoroughly, unless you are fasting; and do not strike your wife as you would strike your slave-girl."

Asim bin Laqit bin Sabirah narrates from his father, who said: I came to the Messenger of Allah (peace and blessings be upon him) as the delegate of Banu al-Muntafiq and said: O Messenger of Allah, tell me about ablution. He (peace and blessings be upon him) said: "Perform ablution well (and completely), pass (water) between the fingers, and sniff water into the nose thoroughly, unless you are fasting."

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Sniff water into the nose thoroughly and blow it out, two or three times."
