"In it are men who love to purify themselves; and Allah loves those who purify themselves."

Yahya: From Hammam, from Qatadah, from Shahr ibn Hawshab who said:

When (the verse) was revealed: "In it are men who love to purify themselves; and Allah loves those who purify themselves," the Messenger of Allah (peace and blessings of Allah be upon him) said: "O assembly of the Ansar, Allah has praised you well regarding purification; so how is your purification with water?" They replied: "We wash the traces of excrement with water," from the hadith of Yahya ibn Muhammad.

Yahya said:

It reached us that the Messenger of Allah (peace and blessings of Allah be upon him) summoned the hypocrites who had built that mosque and said: "What compelled you to build this mosque?" They swore by Allah: "We intended nothing but good," (while) "Allah testifies that they are liars."
