Sayyiduna Usamah bin Zayd (may Allah be pleased with them both) reports about the Prophet (peace and blessings be upon him): "Sayyiduna Jibril (peace be upon him) came to him (peace and blessings be upon him) and taught him ablution. When he finished his ablution, he took a handful of water and sprinkled it towards the private part. The Prophet (peace and blessings be upon him) too used to sprinkle water after his ablution."
Ahmad recorded it; its chain contains a narrator, Rishdin bin Sa'd, whom Haytham bin Kharijah, and Imam Ahmad bin Hanbal according to one report, declared thiqah (trustworthy), while others declared him da'if (weak).
