Quran 2, Al-Baqara (The Cow) ⓘ

2:144We have seen the turning of thy face to heaven (for guidance, O Muhammad). And now verily We shall make thee turn (in prayer) toward a qiblah which is dear to thee. So turn thy face toward the Inviolable Place of Worship, and ye (O Muslims), wheresoever ye may be, turn your faces (when ye pray) toward it. Lo! Those who have received the Scripture know that (this revelation) is the Truth from their Lord. And Allah is not unaware of what they do.

قَدْ نَرَى تَقَلُّبَ وَجْهِكَ فِي السَّمَاءِ فَلَنُوَلِّيَنَّكَ قِبْلَةً تَرْضَاهَا فَوَلِّ وَجْهَكَ شَطْرَ الْمَسْجِدِ الْحَرَامِ وَحَيْثُ مَا كُنْتُمْ فَوَلُّوا وُجُوهَكُمْ شَطْرَهُ وَإِنَّ الَّذِينَ أُوتُوا الْكِتَابَ لَيَعْلَمُونَ أَنَّهُ الْحَقُّ مِنْ رَبِّهِمْ وَمَا اللَّهُ بِغَافِلٍ عَمَّا يَعْمَلُونَ
