If the religion were based on opinion, it would be more important to wipe over the under parts of the leather socks than the upper, but I have seen Allah’s Messenger (rad) wiping over the upper parts of his leather socks. [Reported by Abu Da’ud with good Isnad (chain of narrators)].

When we were on a journey, the Prophet (ﷺ) used to command us to wear our leather socks for three days and three nights, whether we had to answer the call of nature or slept. However, in case of ejaculation or sexual impurity, he commanded us to remove the leather socks. [Reported by An-Nasa’i and At-Tirmidhi, version is of the latter. With them Ibn Khuzaima graded it Sahih (sound)].

Allah’s Messenger (ﷺ) sent out a military expedition and commanded them to wipe over the turbans and leather socks. [ Reported by Ahmad and Abu Da’ud. Al-Hakim graded it Sahih (sound)].

“If one of you performs ablution and puts on his two leather socks, let him perform Mash (wipe) over them and pray in them and he may not take them off he so wishes except after ejaculation or sexual impurity. [Reported by Ad-Daraqutni and Al-Hakim and graded Sahih (sound) by him].

The Prophet (ﷺ) gave permission for the traveller to perform Mash (wiping) over his leather socks for three days and nights and for a non-traveller for a day and night, if he had put them on in a state of purity. [Reported by Ad-Daraqutni and graded Sahih (sound) by Ibnn Khuzaima].

I asked, “O Messenger of Allah, may I wipe over the Khuffain (leather socks)?” The Prophet (ﷺ) replied, “Yes”. I asked, “For one day?” He replied, “For one day”, I again asked, “And for two days?” He replied “For two day s too”. I again asked “And for three days” He replied, “Yes, as long as you wish”. [Reported by Abu Da’ud, who said, “It is not strong”]

Its origin is in Muslim.

and Muslim admitted that he dropped this addition deliberately.

I was one who Madhi (urethral discharge) flowed readily and asked Miqdad (his slave) to ask the Prophet (ﷺ) about it. He (the Prophet) said:“One should perform Wudu (ablution) in this case”. [Agreed upon and this is Al-Bukhari’s version].

The Prophet (ﷺ) kissed one of his wives and went to pray without performing (fresh) ablution. [Reported by Ahmad and Al-Bukhari graded it Da’if (weak)].

And Ahmad said that there is no authentic Hadith in this chapter.

The book written by Allah’s Messenger (ﷺ) for ‘Amr bin Hazm also contained: “ None except a pure person should touch the Quran”. [Reported by Malik as a Mursal and by An-Nasa’i and Ibn Hibban as Mawsul. And it is graded as Ma’lul (defective)].

The Prophet (ﷺ) had blood extracted from his body and offered the prayer and did not perform (a new) ablution. [Reported by Ad-Daraqutni who graded it Da’if (weak)].
