´It was narrated from Sa'eed bin 'Abdur-Rahman bin Abza from his father, that:` A man came to 'Umar bin khattab and said: "I became impure following sexual emission and cannot find any water." 'Umar said to him: "Do not pray." But 'Ammar bin Yasir said: "Do you not remember, O Commander of the Believers, when you and I were on a military expedition and we became sexually impure and could not find water? As for you, you did not pray, but I rolled in the dust and then prayed. When I came to the Prophet and told him what had happened, he said: 'It would have been enough for you (to do this).' (Then demonstrating) the Prophet struck the ground with his hands, then blew on hem, and wiped his face and palms with them."

´It was narrated that Ubayy bin Ka’b said:` “The Messenger of Allah (ﷺ) used to perform Witr and recite: ‘Glorify the Name of your Lord the Most High.’, [Al-A’la (87)] ‘Say: O you disbelievers!” [Al-Kafirun (109)] and ‘Say: Allah is One.”. [Al-Ikhlas (112)]

It was narrated from Ubayy bin Ka’b that the Messenger of Allah (ﷺ) used to pray Witr and he would recite Qunut before Ruku’.

´It was narrated that Abu Mujalid said:` "Abdullah bin Shaddad and Abu Barzah had a dispute about paying in advance. They sent me to 'Abdullah bin Abu Awfa to ask him about it. He said: 'We used to make payments in advance at the time of the Messenger of Allah (ﷺ) and the time of Abu Bakr and 'Umar, for wheat, barley, raisins and dates, to people who did not yet possess those things.' I asked Ibn Abza, and he said something similar."
