Qur'an 3:157 · Aal-i-Imraan

وَلَئِن قُتِلْتُمْ فِى سَبِيلِ ٱللَّهِ أَوْ مُتُّمْ لَمَغْفِرَةٌۭ مِّنَ ٱللَّهِ وَرَحْمَةٌ خَيْرٌۭ مِّمَّا يَجْمَعُونَ

(157) 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].
