Sunan an-Nasa'i, Volume 2, Book 13, Hadith 1238 (DarusSalam) ⓘ

It was narrated that Imran bin Husain said: "The Messenger of Allah said the salam after three rak'ahs of 'Asr, then he entered his house. A man called Al-Khibaq stood up and said: 'Has the prayer been shortened, O Messenger of Allah?' He came out angry, dragging his upper garment and said: 'Is he speaking the truth?' They said: 'Yes.' So he stood and prayed that rak'ah, then he said the salam, then prostrated twice, then he said the salam (again)."

أَخْبَرَنَا أَبُو الأَشْعَثِ، عَنْ يَزِيدَ بْنِ زُرَيْعٍ، قَالَ حَدَّثَنَا خَالِدٌ الْحَذَّاءُ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَبِي الْمُهَلَّبِ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، قَالَ سَلَّمَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي ثَلاَثِ رَكَعَاتٍ مِنَ الْعَصْرِ فَدَخَلَ مَنْزِلَهُ فَقَامَ إِلَيْهِ رَجُلٌ يُقَالُ لَهُ الْخِرْبَاقُ فَقَالَ يَعْنِي نَقَصَتِ الصَّلاَةُ يَا رَسُولَ اللَّهِ فَخَرَجَ مُغْضَبًا يَجُرُّ رِدَاءَهُ فَقَالَ ‏ "‏ أَصَدَقَ ‏" ‏ ‏.‏ قَالُوا نَعَمْ ‏.‏ فَقَامَ فَصَلَّى تِلْكَ الرَّكْعَةَ ثُمَّ سَلَّمَ ثُمَّ سَجَدَ سَجْدَتَيْهَا ثُمَّ سَلَّمَ ‏.‏
