Abdul Razzaq al-Badr said,
Khuff is a well known type of socks. It is made of leather and it covers the entire foot.
73. Buraydah narrated: “Al-Najāshī sent two plain black coloured khuffs as a gift to the Messenger of Allāh (peace be upon him). As soon as he received them, he tried them on, performed ablution and then wiped over them.” [89]
Abdul Razzaq al-Badr said,
“Al-Najāshī” was the title given to the kings of Ethiopia and the name of this particular king was As-Hamah; he embraced Islām and died upon it. When he died, the Prophet (peace be upon him) prayed the absentee funeral prayer on him.
Al-Bajūrī said,
“As soon as he received them, he tried them on”: This indicates that when a person receives a gift from someone, using it immediately shows one’s acceptance of the gift and it also indicates the continuous signals of love between the one receiving the gift and the sender of gift. This hadīth also indicates that one should accept gifts even if they come from the people of the book because at that time al-Najāshī was still a disbeliever, as stated by Abū Bakr ibn al-Arabī.
Ibn Hajar al-Haytamī said,
“Performed ablution and then wiped over them”: This indicates that when an object’s purity cannot be ascertained, it is deemed to be pure. It also indicates the permissibility of wiping over the khuff.
74. Al-Mughīrah ibn Shu’bah narrated: “Dihiyyah gifted the Prophet (peace be upon him) with a pair of khuffs that he wore right away and he kept wearing them until they became torn. The Prophet (peace be upon him) did not know whether the skin of the khuffs was from an animal that was slaughtered properly or not.”
From another route, it adds, “He was also gifted a robe that he wore until it became torn.” [90]
Abdul Razzaq al-Badr said,
“That he wore right away”: This teaches us to hasten in accepting the gift and to use it right away so as to make the one who gave the gift happy and pleased.
Alī al-Qārī said,
“The Prophet (peace be upon him) did not know whether the skin of the khuffs was from an animal that was slaughtered properly or not”: [The companion reported this] because either he (peace be upon him) stated it, or the companion determined this because the Prophet (peace be upon him) did not inquire about it.
Al-Bajūrī said,
“Until they became torn”: This indicates that the Prophet (peace be upon him) used to keep wearing the clothes he had until they became worn out, as this is from humility.
