وَأَصْلِحْ لِي فِي ذُرِّيَّتِي إِنِّي تُبْتُ إِلَيْكَ وَإِنِّي مِنَ الْمُسْلِمِينَ
Wa aslih li fi dhurriyyati inni tubtu ilayka wa inni minal-Muslimin
And set right for me my offspring. Indeed, I have repented to You, and indeed I am of the Muslims.
"Aslih" — rectify, set right, fix. This du'a acknowledges that your children may have problems you cannot solve — behavioral issues, spiritual crises, worldly difficulties. You ask Allah to fix what is broken in your offspring. And the tie to repentance is deliberate: your own tawbah purifies the soil in which your family grows. A parent's spiritual state directly affects their children.
