فَمَآ أُوتِيتُم مِّن شَىْءٍۢ فَمَتَٰعُ ٱلْحَيَوٰةِ ٱلدُّنْيَا ۖ وَمَا عِندَ ٱللَّهِ خَيْرٌۭ وَأَبْقَىٰ لِلَّذِينَ ءَامَنُوا۟ وَعَلَىٰ رَبِّهِمْ يَتَوَكَّلُونَ
Now whatever ye have been given is but a passing comfort for the life of the world, and that which Allah hath is better and more lasting for those who believe and put their trust in their Lord,
