Sahih al-Bukhari 391
Sahih al-Bukhari · Book 8: Prayers (Salat) · Superiority of (praying) facing the Qiblah with the toes toward it as well
Narrated Anas bin Malik:
حَدَّثَنَا عَمْرُو بْنُ عَبَّاسٍ ، قَالَ حَدَّثَنَا ابْنُ الْمَهْدِيِّ ، قَالَ حَدَّثَنَا مَنْصُورُ بْنُ سَعْدٍ ، عَنْ مَيْمُونِ بْنِ سِيَاهٍ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ صَلَّى صَلاَتَنَا، وَاسْتَقْبَلَ قِبْلَتَنَا، وَأَكَلَ ذَبِيحَتَنَا، فَذَلِكَ الْمُسْلِمُ الَّذِي لَهُ ذِمَّةُ اللَّهِ وَذِمَّةُ رَسُولِهِ، فَلاَ تُخْفِرُوا اللَّهَ فِي ذِمَّتِهِ " .
Allah's Messenger (ﷺ) said, "Whoever prays like us and faces our Qibla and eats our slaughtered animals is a Muslim and is under Allah's and His Apostle's protection. So do not betray Allah by betraying those who are in His protection."
