I said to Umar bin Al-Khattâb " Remember that ' you and I (became Junub while both of us) were together on a journey and you didn't offer (prayer) but I rolled myself on the ground and offered (prayer)? I informed the Prophet (ﷺ) about it and he said, 'It would have been sufficient for you to do like this. ' The Prophet (ﷺ) I then stroked lightly the earth with his hands and then blew off the dust and passed his hands over his face and hands." [1:334-O.B.]
