Explanation

The Prophet Muhammad (ﷺ) famously remarked: "Surah Hud and its sisters have made me grow old." 

Surah Hud that many scholars attribute this statement to is Ayah 112:

فَٱسْتَقِمْ كَمَآ أُمِرْتَ وَمَن تَابَ مَعَكَ وَلَا تَطْغَوْا۟ ۚ إِنَّهُۥ بِمَا تَعْمَلُونَ بَصِيرٌ

"So remain steadfast as you have been commanded, [you] and those who have turned back [to Allah] with you, and do not transgress. Indeed, He is Seeing of what you do." (Surah Hud, 11:112)
