That the Messenger of Allah (ﷺ) said: “Any skin tanned, then it has been made pure.” This Hadith is Hasan Sahih. This is acted upon according to most of the people of knowledge, they say that when the skin of a dead animal has been tanned then it has been made pure. Ash-Shafi’i said: “Any dead animals skin that is tanned, then it has been made pure, except for the dog and the pig.” Some of the people of knowledge among the Companions of the Prophet (ﷺ) disliked skins of predators even when tanned, and this is the view of ‘Abdullah bin Al-Mubarak, Ahmad and Ishaq, and they were firm about not wearing them and performing Salat in them. Ishaq bin Ibrahim said: “The saying of the Prophet (ﷺ):’Any skin that is tanned, then it has been made pure’ only refers to the skins of animals whose meat is eaten.” This is how it was explained by An-Nasr bin Shumail.
“I prayed with ‘Abdullah bin Abi Awfa Al-Aslami, the Companion of the Messenger of Allah (ﷺ), offering the funeral prayer for a daughter of his. He said Takbir over her four times, and he paused for a while after the fourth. I heard the people saying Subhan- Allah to him throughout the rows. Then he said the Salam and said: ‘Did you think that I was going to say a fifth Takbir?’ They said: ‘We were afraid of that.’ He said: ‘I was not going to do that, but the Messenger of Allah (ﷺ) used to say four Takbir, then pause for a while, and he would say whatever Allah willed he should say, then he would say the Salam.’”
“This Verse was revealed concerning us six: Myself, Ibn Mas’ud, Suhaib, ‘Ammar, Miqdad and Bilal. The Quraish said to the Messenger of Allah (ﷺ): ‘We do not want to join them, send them away.’ Thoughts of that entered the heart of the Messenger of Allah (ﷺ) as much as Allah willed, then Allah revealed: “And turn not away those who invoke their Lord, morning and afternoon seeking His Face. You are accountable for them in nothing, and they are accountable for you in nothing, that you may turn them away, and thus become of the unjust.”
