Hazrat Anas bin Malik, Allah be pleased with him, narrates that the Holy Prophet, peace and blessings of Allah be upon him, said:
“Whoever prays like us and faces our Qibla and eats our slaughtered animals is a Muslim and is under Allah’s and His Prophet’s protection. So do not betray Allah by betraying those who are in His protection.”
(Sahih al-Bukhari, Kitab al-Salat)
