in Edition Clear Qur'an by Talal Itani / Aal-i-Imraan (The Family of Imraan)

3:81God received the covenant of the prophets, “Inasmuch as I have given you of scripture and wisdom; should a messenger come to you verifying what you have, you shall believe in him, and support him.” He said, “Do you affirm My covenant and take it upon yourselves?” They said, “We affirm it.” He said, “Then bear witness, and I am with you among the witnesses.”

3:178Those who disbelieve should not assume that We respite them for their own good. In fact, We only respite them so that they may increase in sinfulness. A humiliating torment awaits them.

3:180Those who withhold what God has given them of his bounty should not assume that is good for them. In fact, it is bad for them. They will be encircled by their hoardings on the Day of Resurrection. To God belongs the inheritance of the heavens and the earth, and God is well acquainted with what you do.
