Please read this narration that Ammar bin Yasir reminded Umar bin Khattab about Tayammum
The next narration makes more clear that Umar bin Khattab was not agree about Tayammum
It is not a light thing that someone uses his own mind vs Quranic orders. We are surprised that sunni school of thought gives these rights to companions. We are unable to get it that someone spent his half life in idols worshiping after entering in Islam, he gets the authority to change the sharia law and he can use his own mind against Allah’s orders. Unfortunatly this is the true picture of Sunni Islam.
