Messenger of Allah 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." (Using translation from Bukhārī 391)
قَالَ رَسُولُ اللهِ ﷺ مَنْ صَلَّى صَلَاتَنَا وَاسْتَقْبَلَ قِبْلَتَنَا وَأَكَلَ ذَبِيحَتَنَا فَذَلِكَ الْمُسْلِمُ لَهُ ذِمَّةُ اللهِ وَذِمَّةُ رَسُولِهِ فَلَا تُخْفِرُوا اللهَ فِي ذِمَّتِهِ
