The Women - 4:57
And those who believe and do righteous deeds, We will place them in gardens in which rivers flow; there they will abide forever. For them therein are immaculate wives. We will put them in cool shade.
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."
