سنن أبي داود

Ubayy b. Ka’b said: There was a certain person, out of all people of Medina, who used to pray in the mosque. I do not know that any one of them lived at a farther distance than that man. Still he never missed the prayer in congregation in the mosque. I said: it would be better if you buy a donkey and ride it in heat and darkness. He said: I do not like that my house be by the side of the mosque. The discourse reached the Messenger of Allah (ﷺ). He said him about it. He said: I did it so that my walking to the mosque and return to my home when I return be recorded. He said: Allah has granted all this to you; Allah has granted all that you reckoned.
