Sahih Muslim 694e
Ibn 'Umar reported: The Apostle of Allah ﷺ said in Mina the prayer of a traveller (short prayer) ;
Abu Bakr and 'Umar did the same and 'Uthmia did it for eight years or six years. Hafs (one of the narrators) said: Ibn 'Umar would also say two rak'ahs at Mina and then go to bed. I said to him: O uncle, I wish you could have said two rak'ahs (of Sunnah prayer after shorenting the Fard prayer). He said: Were I to do that, I would have completed the prayer.
وَحَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ خُبَيْبِ بْنِ عَبْدِ الرَّحْمَنِ، سَمِعَ حَفْصَ بْنَ عَاصِمٍ، عَنِ ابْنِ عُمَرَ، قَالَ صَلَّى النَّبِيُّ ﷺ بِمِنًى صَلاَةَ الْمُسَافِرِ وَأَبُو بَكْرٍ وَعُمَرُ وَعُثْمَانُ ثَمَانِيَ سِنِينَ أَوْ قَالَ سِتَّ سِنِينَ . قَالَ حَفْصٌ وَكَانَ ابْنُ عُمَرَ يُصَلِّي بِمِنًى رَكْعَتَيْنِ ثُمَّ يَأْتِي فِرَاشَهُ . فَقُلْتُ أَىْ عَمِّ لَوْ صَلَّيْتَ بَعْدَهَا رَكْعَتَيْنِ . قَالَ لَوْ فَعَلْتُ لأَتْمَمْتُ الصَّلاَةَ .
