From ʿAlī (may Allah be pleased with him), who said: I memorised from the Messenger of Allah (peace and blessings be upon him): «There is no orphanhood after a nocturnal emission, nor ritual silence for a day until the night.» It was narrated by Abū Dāwūd with a chain that is good (ḥasan). Al-Khaṭṭābī said in his commentary on this hadith: ritual silence was among the rites of the pre-Islamic era. In Islam they were forbidden from that and were commanded with remembrance and speaking of good.
