A Muslim has a special prayer they make when they hit the special midlife age of forty (40) years. At this age, strength meets wisdom, and then strength reduces as the person gets older and wisdom takes over.

It’s a prayer of Gratitude, and for Good deeds and Righteous offspring, in Repentance and Submission.

The prayer is presented in this Quranic verse in surah al-Layl:

وَوَصَّيْنَا ٱلْإِنسَـٰنَ بِوَٰلِدَيْهِ إِحْسَـٰنًا ۖ حَمَلَتْهُ أُمُّهُۥ كُرْهًۭا وَوَضَعَتْهُ كُرْهًۭا ۖ وَحَمْلُهُۥ وَفِصَـٰلُهُۥ ثَلَـٰثُونَ شَهْرًا ۚ حَتَّىٰٓ إِذَا بَلَغَ أَشُدَّهُۥ وَبَلَغَ أَرْبَعِينَ سَنَةًۭ قَالَ رَبِّ أَوْزِعْنِىٓ أَنْ أَشْكُرَ نِعْمَتَكَ ٱلَّتِىٓ أَنْعَمْتَ عَلَىَّ وَعَلَىٰ وَٰلِدَىَّ وَأَنْ أَعْمَلَ صَـٰلِحًۭا تَرْضَىٰهُ وَأَصْلِحْ لِى فِى ذُرِّيَّتِىٓ ۖ إِنِّى تُبْتُ إِلَيْكَ وَإِنِّى مِنَ ٱلْمُسْلِمِينَ

We have commanded people to honour their parents. Their mothers bore them in hardship and delivered them in hardship. Their ˹period of˺ bearing and weaning is thirty months. In time, when the child reaches their prime at the age of forty, they pray, “My Lord! Inspire me to ˹always˺ be thankful for Your favors which You blessed me and my parents with, and to do good deeds that please You. And instill righteousness in my offspring. I truly repent to You, and I truly submit ˹to You˺.”
