Sahih Muslim 694 e
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 صلى الله عليه وسلم 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 ‏.‏
