Ar-Rum - 30:54

اللَّهُ الَّذِي خَلَقَكُم مِّن ضَعْفٍ ثُمَّ جَعَلَ مِن بَعْدِ ضَعْفٍ قُوَّةً ثُمَّ جَعَلَ مِن بَعْدِ قُوَّةٍ ضَعْفًا وَشَيْبَةً يَخْلُقُ مَا يَشَاء وَهُوَ الْعَلِيمُ الْقَدِيرُ
[30:54]
Allah is He Who created you from a state of weakness then He gave strength after weakness, then ordained weakness and hoary hair after strength; He creates what He pleases, and He is the Knowing, the Powerful.
