Abd al-Rahman bin Abza (may Allah be pleased with him) said: I was with Sayyiduna Umar (may Allah be pleased with him), and he mentioned the hadith. Sayyiduna Ammar (may Allah be pleased with him) said: I came to the Prophet (peace and blessings be upon him) and mentioned this to him (peace and blessings be upon him). He (peace and blessings be upon him) said: "It would have sufficed you to do like this," and he struck the ground with his hands, then blew, and wiped his face and his hands up to the middle of the forearms.
