Sunan ad-Darimi

Sayyiduna Abu Hurairah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) led one of the two noon prayers, and after praying two rak‘ahs, he ended the prayer with salam. Then he stood by a piece of wood kept in the mosque and leaned on it with his hand. Yazid bin Harun said: Ibn ‘Aun showed us by placing one hand on the back of the other and interlacing the fingers of the upper hand with those of the lower hand. When the Prophet (peace and blessings be upon him) stood, it seemed as if he was angry. Those who were quick to leave, left, and they began to say, “The prayer has been shortened, the prayer has been shortened.” Among those present were Abu Bakr and ‘Umar (may Allah be pleased with them both), but they did not have the courage to speak. Among the people was a man who was called Dhu’l-Yadayn (the one with long arms). He said, “O Messenger of Allah! Did you forget, or has the prayer been shortened?” He replied, “I did not forget, nor has the prayer been shortened.” Then he asked those present, “Has this happened?” (i.e., was there any deficiency in the prayer?) They replied, “Yes.” So the Prophet (peace and blessings be upon him) returned and completed the prayer, then ended it with salam. Then he said “Allahu Akbar” and performed a long prostration, then raised his head, then said takbir again and performed a second prostration like the first, then raised his blessed head from prostration and turned around.
