Yahya related to me from Malik from Ayyub ibn Abi Tamima as-
Sakhtayani from Muhammad ibn Sirin that Umar ibn al-Khattab was with
some people who were reciting Quran. He went to relieve himself and
then came back and recited Quran. One of the men said to him, "Amir
al muminin, are you reciting the Quran without being in wudu?" Umar
replied, "Who gave you a verdict on this? Was it Musaylima?"'
