Surah Ali 'Imran — Ayah 157 (3:157)
وَلَئِن قُتِلۡتُمۡ فِي سَبِيلِ ٱللَّهِ أَوۡ مُتُّمۡ لَمَغۡفِرَةٞ مِّنَ ٱللَّهِ وَرَحۡمَةٌ خَيۡرٞ مِّمَّا يَجۡمَعُونَ ١٥٧
English translation (Saheeh International)
And if you are killed in the cause of Allāh or die - then forgiveness from Allāh and mercy are better than whatever they accumulate [in this world].
Brief commentary
If you are killed or die in Allah’s path, O believers, Allah will forgive you and be merciful with you, and that is better than this world along with what the people of this world collect of its passing pleasures.
