Narrated from Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Three persons were presented to me who will enter Paradise first: a martyr, the one who keeps away from the unlawful and avoids inappropriate matters, and the slave who worships Allah well and wishes good for his masters or fulfills their rights." Imam Tirmidhi says: This hadith is Hasan.
