Al-‘Abbas b. ‘Abd al-Muttalib reported God’s messenger as saying, “He who is well-pleased with God as Lord, with Islam as religion, and with Muhammad as messenger will experience the savour of faith,”
Narrated He also reported God’s messenger as saying, “There are three qualities for which anyone who is characterised by them will experience the sweetness of faith:
he to whom God and His messenger are dearer than all else; he who loves a human being for God’s sake alone; and he who has as great an abhorrence of returning to unbelief after God has rescued him from it as he has of being cast into hell.”
Abu Huraira reported God’s messenger as saying, "By Him in whose hand Muhammad’s soul is, anyone of this people, Jew or Christian, who hears of me and then dies without believing in my message, will be among those who go to hell.”
