Sayyiduna Imran bin Husain (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) concluded the ‘Asr prayer after three rak‘ahs. Sayyiduna Khirbaq (may Allah be pleased with him) submitted to him: O Messenger of Allah (peace be upon him)! Did you forget, or has the prayer been shortened? The Prophet (peace be upon him) asked: Is Khirbaq speaking the truth? They replied: Yes! You stood up, performed one rak‘ah, performed the prostration of forgetfulness twice, and then concluded the prayer with salam.
