Just now my father shared with me this ayat, which I would like to in turn share with you, especially those 35 years old and above. It's a doa that Allah teaches us, when we reach 40 years of age.
وَوَصَّيْنَا الْإِنسَانَ بِوَالِدَيْهِ إِحْسَانًا حَمَلَتْهُ أُمُّهُ كُرْهًا وَوَضَعَتْهُ كُرْهًا وَحَمْلُهُ وَفِصَالُهُ ثَلَاثُونَ شَهْرًا حَتَّى إِذَا بَلَغَ أَشُدَّهُ وَبَلَغَ أَرْبَعِينَ سَنَةً قَالَ رَبِّ أَوْزِعْنِي أَنْ أَشْكُرَ نِعْمَتَكَ الَّتِي أَنْعَمْتَ عَلَيَّ وَعَلَى وَالِدَيَّ وَأَنْ أَعْمَلَ صَالِحًا تَرْضَاهُ وَأَصْلِحْ لِي فِي ذُرِّيَّتِي إِنِّي تُبْتُ إِلَيْكَ وَإِنِّي مِنَ الْمُسْلِمِينَ
أُوْلَئِكَ الَّذِينَ نَتَقَبَّلُ عَنْهُمْ أَحْسَنَ مَا عَمِلُوا وَنَتَجاوَزُ عَن سَيِّئَاتِهِمْ فِي أَصْحَابِ الْجَنَّةِ وَعْدَ الصِّدْقِ الَّذِي كَانُوا يُوعَدُونَ
We have enjoined on man kindness to his parents: In pain did his mother bear him, and in pain did she give him birth. The carrying of the (child) to his weaning is (a period of) thirty months. At length, when he reaches the age of full strength and attains forty years, he says, "O my Lord! Grant me that I may be grateful for Thy favour which Thou has bestowed upon me, and upon both my parents, and that I may work righteousness such as Thou mayest approve; and be gracious to me in my issue. Truly have I turned to Thee and truly do I bow (to Thee) in Islam."
Such are they from whom We shall accept the best of their deeds and pass by their ill deeds: (They shall be) among the Companions of the Garden: a promise! of truth, which was made to them (in this life).
Al-Ahqaf 46:15-16 (translation by Yusuf Ali)
