Abu Hashim al-Rmany أبو هاشم الرماني · The Book of Purification

"I said: 'O Messenger of Allah, tell me about Wudu." He said: 'Perform Wudu' well, and exxagerate in sniffing water up into your nose, except when you are fasting.'" See No. 141

The Messenger of Allah (ﷺ) said: "When you perform Wudu', do so properly, and wash in between the fingers (Al-Asabi')." Al-Asabi' is plural meaning fingers as well as toes, and the author mentioned only one narration on the topic whereas some of them clarify "of the hands and feet." So he mentioned the general wording amids chapters how to wash the feet. Part of this narration preceded under No. 87.

"I remember when I could do no more than rub it form the garment of the Messenger of Allah (ﷺ)."
