Quran 5:68 — The Feast (Al-Ma'edah)

Say, "O people of the scripture, you have no basis until you uphold the Torah, and the Gospel, and what is sent down to you herein from your Lord." For sure, these revelations from your Lord will cause many of them to plunge deeper into transgression and disbelief. Therefore, do not feel sorry for the disbelieving people.

[5:67] O you messenger, deliver what is revealed to you from your Lord—until you do, you have not delivered His message—and GOD will protect you from the people. GOD does not guide the disbelieving people.

[5:69] Surely, those who believe, those who are Jewish, the converts, and the Christians; any of them who (1) believe in GOD and (2) believe in the Last Day, and (3) lead a righteous life, have nothing to fear, nor will they grieve.
