Quran 3:170 — The Amramites (Ali-'Imran)

فَرِحينَ بِما ءاتىٰهُمُ اللَّهُ مِن فَضلِهِ وَيَستَبشِرونَ بِالَّذينَ لَم يَلحَقوا بِهِم مِن خَلفِهِم أَلّا خَوفٌ عَلَيهِم وَلا هُم يَحزَنونَ

They are rejoicing in GOD's grace, and they have good news for their comrades who did not die with them, that they have nothing to fear, nor will they grieve.

[3:169] Do not think that those who are killed in the cause of GOD are dead; they are alive at their Lord, enjoying His provisions.

[3:171] They have good news of GOD's blessings and grace, and that GOD never fails to reward the believers.
