Sahih al-Bukhari, Hadith 391 ⓘ
Narrated Anas bin Malik: Allah's Messenger 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."
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 " .
