Hazrat Hakam bin Aban narrates that Hazrat Ikrimah was with a group and I was with another group. Hazrat Ikrimah’s group did not have water, so they performed tayammum and offered prayer. Then, when they reached the place where there was water, Hazrat Ikrimah said to them,“Do you see the sun over the mountains?”The people replied,“No.”Hazrat Ikrimah said,“Even if you had seen the sun, we would not repeat the prayer because tayammum is sufficient for us.”Then, when I reached the place of Jund, I met Amr bin Muslim, a student of Hazrat Tawus. I mentioned Hazrat Ikrimah’s statement to him, so he went to Hazrat Tawus and mentioned this to him. Then he returned to me and informed me that he had mentioned Ikrimah’s statement to Hazrat Tawus, and he said,“He speaks the truth.”
