It is narrated from Hazrat Abu Al-Hakam or Hakam (may Allah be pleased with him) that once he saw the Prophet (peace and blessings be upon him) urinate, then perform ablution, and then sprinkle some water on his private part. Shareek (may Allah have mercy on him) says that he asked the family of Hakam bin Sufyan, and they informed him that he had not met the Prophet (peace and blessings be upon him). The previous hadith is also narrated through this second chain.
