"We were with the Prophet on a journey on a very dark night and we did not know the direction of the Qiblah. So each man among us prayed in his own direction. In the morning when we mentioned that to the Prophet, then the following was revealed: So where ever you turn, there is the Face of Allah."  

كُنَّا مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ فِي لَيْلَةٍ مُظْلِمَةٍ فَلَمْ نَدْرِ أَيْنَ الْقِبْلَةُ فَصَلَّى كُلُّ رَجُلٍ مِنَّا عَلَى حِيَالِهِ فَلَمَّا أَصْبَحْنَا ذَكَرْنَا ذَلِكَ لِلنَّبِيِّ ﷺ فَنَزَلَ (فَأَيْنَمَا تُولُّوا فَثَمَّ وَجْهُ الله)
