Imran bin Husayn reported,

The Messenger of Allah ﷺ prayed the afternoon prayer and gave the closing salutation after only three units. He then entered his home, and a man called al-Khirbaq, who had long arms, stood up and approached him.He said, "Messenger of Allah," and pointed out to him what he had done.The Prophet ﷺ came out angry, dragging his cloak, until he reached the people and asked, "Is what this man says true?"They replied, "Yes."So he prayed one more unit, then gave the closing salutation, performed two prostrations, and gave the closing salutation again.

عن عمران بن حصين

أن رسول الله ﷺ صلى العصر فسلم في ثلاث ركعات، ثم دخل منزله، فقام إليه رجل يقال له الخرباق، وكان في يديه طول، فقال: يا رسول الله! فذكر له صنيعه، وخرج غضبان يجر رداءه حتى انتهى إلى الناس فقال: أصدق هذا؟ قالوا: نعم. فصلى ركعة، ثم سلم، ثم سجد سجدتين، ثم سلم.
