Aamir says that a man came to Sayyiduna Ibn Amr (may Allah be pleased with him) while some people were already sitting with him. He began to step over their necks. The people stopped him, but Sayyiduna Ibn Amr (may Allah be pleased with him) said: "Let him be." He came and sat with them and said, "Tell me a hadith that you have preserved from the Prophet (peace and blessings be upon him)." He replied: "I heard the Prophet (peace and blessings be upon him) say that a Muslim is one from whose tongue and hand other Muslims are safe, and a Muhajir is one who abandons what Allah has forbidden."
