Yahya related to me from Malik from Ismail ibn Abi Hakim from
Sulayman ibn Yasar that Umar ibn al-Khattab went out early in the
morning to his land in al-Juruf and found semen on his garment. He
said, "I have been tried with wet dreams since I have been entrusted
with governing the people." He did ghusl and washed his garment of
what he saw of the semen, and then prayed after the sun had risen.
