on the authority of Amr bin Abasah, that a man came to RasulAllah (saw), saying: "O RasulAllah (saw)! What is Islam? RasulAllah (saw) replied: It is that you submit your heart to Allah, and that you protect the Muslims from your tongue and hand. The man then asked: Which Islam is the best? RasulAllah (saw) replied: Iman. The man asked: And what is Iman? RasulAllah (saw) said: That you believe in Allah, His Angels, His Books, His Messengers, and the Resurrection after death. The man asked: Which Iman is the best? RasulAllah (saw) said: Hijrah. The man asked: And what is hijrah? RasulAllah (saw) said: That you abandon evil. The man asked: And which hijrah is the best? RasulAllah (saw) replied: Jihaad."
