4 – Wiping over the khuffs and the like is a concession from Allah, a means of ease for His servants; the Prophet ﷺ who conveyed it was transmitting what Allah had authorized.
5 – The more acute the need, the broader the concession and facilitation that the Law provides. This is one of Islam’s major, overarching principles in its judicious rulings.
6 – The wording “he granted a concession” shows that wiping over the khuffs is a rukhṣah (concession), not an ʿazīmah (strict, original ruling). Because a concession is by definition not obligatory, wiping over the khuffs is therefore not compulsory.
7 – Linguistically, a rukhṣah means “ease.” Technically, it is a ruling established contrary to an original scriptural proof because of a stronger, overriding consideration. In this issue, the original proof is the obligation to wash the feet during wuḍūʾ and to wipe the head, while the overriding consideration is the allowance of ease by wiping.
8 – The hadith also demonstrates that the Sacred Law addresses those legally responsible in accordance with their circumstances; every individual is given the ruling that best fits his particular state.
