Imam Bukhari narrates: Ibn Abi Maryam said: Yahya informed us, he said: Humaid narrated to us, he said: Hazrat Anas, Allah be pleased with him, narrated to us from the Prophet ﷺ. And Ali bin Abdullah said: Khalid bin al-Harith narrated to us, he said: Humaid narrated, he said:
Maimun bin Siyah asked Hazrat Anas bin Malik, Allah be pleased with him, and said: O Abu Hamza! What is it that makes the life and property of a servant unlawful? So he said: Whoever bore witness that there is no god but Allah, and turned his face towards our qiblah, and prayed in our manner, and ate our slaughtered animal, then he is a Muslim. He has those rights which are the rights of a Muslim, and upon him are obligatory those rulings which are obligatory upon a Muslim.
