Prophet Abraham - 14:23 "Those who believe and do righteous deeds will be admitted into Gardens from which rivers flow. They will stay there permanently by the permission of their Lord. Their wish therein is, "Peace be upon you"."
The most important criterion of faith:
The Companies/39:65 It has been revealed to you and those before you that if you associate partners, all that you do will be in vain and you will be of the losers.

The Cattle/6:82 Those who believe and do not mix their faith with wrongdoing, they deserve security and they have found the truth.

Luqman/31:13 "When Lokman advised his son, he said: "My dear son, do not associate partners with Allah; surely shirk (associating partners with God) is a great wrong."
