A man was praying with his lower garment hanging down. The Messenger of Allah (ﷺ) said to him: Go and perform ablution. He then went and performed ablution. He then came and he said: Go and perform ablution. Then a man said to him: Messenger of Allah, what is the matter with you that you commanded him to perform ablution and then you kept silence ? He replied: He was praying while hanging down his lower garments, and Allah does not accept the prayer of a man who hangs down his lower garment.

The Prophet (ﷺ) as saying: There are three to whom Allah will not speak and at whom He will not look on the Day of Resurrection, and whom He will not declare pure, and they will have a painful punishment.
