The Statement of Allah "Verily! We have seen the turning of your (Muhammad's ) face towards the heaven..." (V.2:144)

Sahih al-Bukhari · Book 65 · Hadith 4489

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا مُعْتَمِرٌ، عَنْ أَبِيهِ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ لَمْ يَبْقَ مِمَّنْ صَلَّى الْقِبْلَتَيْنِ غَيْرِي‏.‏

Narrated Anas: None remains of those who prayed facing both Qiblas (that is, Jerusalem and Mecca) except myself.
