Surah Al-Kahf — Ayah 24 (18:24)
إِلَّآ أَن يَشَآءَ ٱللَّهُۚ وَٱذۡكُر رَّبَّكَ إِذَا نَسِيتَ وَقُلۡ عَسَىٰٓ أَن يَهۡدِيَنِ رَبِّي لِأَقۡرَبَ مِنۡ هَٰذَا رَشَدٗا ٢٤
English translation (Saheeh International)
Except [when adding], "If Allāh wills." And remember your Lord when you forget [it] and say, "Perhaps my Lord will guide me to what is nearer than this to right conduct."
Brief commentary
Unless you suspend doing so on Allah’s will by saying: I will do it - if Allah wills - tomorrow. Remember your Lord by saying: “If Allah wills” - if you forget to say it - and say: I have hope that my Lord will guide me to something closer than this in guidance and success.
