Musannaf Ibn Abi Shayba 1:1782

Al-Hasan ibn Musa narrated to us, he said: Ibn Lahi'ah narrated to us, from 'Aqil, from Ibn Shihab, from 'Urwah, from Usamah ibn Zayd ibn Harithah, from his father, that the Prophet (peace and blessings of Allah be upon him) performed ablution, then he took a handful of water and sprinkled it over his private part.
