Quran 3:138 — The Amramites (Ali-'Imran)
This is a proclamation for the people, and a guidance and enlightenment for the righteous.
[3:137] Precedents have been set for you in the past; roam the earth and note the consequences for the unbelievers.
[3:139] You shall not waver, nor shall you grieve, for you are the ultimate victors, if you are believers.
