Surah Al-Kahf — Ayah 39 (18:39)
وَلَوۡلَآ إِذۡ دَخَلۡتَ جَنَّتَكَ قُلۡتَ مَا شَآءَ ٱللَّهُ لَا قُوَّةَ إِلَّا بِٱللَّهِۚ إِن تَرَنِ أَنَا۠ أَقَلَّ مِنكَ مَالٗا وَوَلَدٗا ٣٩
English translation (Saheeh International)
And why did you, when you entered your garden, not say, 'What Allāh willed [has occurred]; there is no power except in Allāh'? Although you see me less than you in wealth and children,
Brief commentary
If only, when you entered your garden, you had said: As Allah wills. No one has any power except through Allah. He is the One Who does as He pleases and He is the One of strength- if you regard me as someone poorer than you and one with less children.
