Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrates: The Prophet (peace and blessings of Allah be upon him) led those people in prayer. He performed the prostration of forgetfulness (sajda sahw) twice, then he recited the tashahhud and concluded the prayer with salam. In narrating this report, the narrator named Ansari is unique; Ibn Sirin has not narrated any other report from Khalid except this hadith, although Khalid is his student.
