Answered by Shaykh Faraz Rabbani
Question: Assalamu alaykum
Is the prayer valid if one prays in impure clothes but had no clue of them being impure at that time?
Does one have to repeat all of those prayers?
Answer: Walaikum assalam,
I hope you’re doing well, insha’Allah.
The base assumption of all objects is that they are pure, unless certainly established otherwise. Likewise, the base assumption of all actions is validity, unless certainly established otherwise. [Ala’ al-Din Abidin, al-Hadiyya al-`Ala’iyya; Tahtawi/Shurunbulali, Hashiyat Maraqi al-Falah; Ibn Abidin, Radd al-Muhtar]
Hold fast to those two assumptions; assume that your clothes were pure (or, if there was impurity, it was excusable)—and that your past prayers were valid. Ignore doubts.
Be grateful to Allah Most High for the blessing of ease in religion. Allah Most High tells us, “And He has placed no hardship for you in religion.” [Qur’an, 22.78]

And Allah is the giver of success and facilitation.
