وَلَا تَقُولَنَّ لِشَيْءٍ إِنِّي فَاعِلٌ ذَٰلِكَ غَدًا (۲۳)إِلَّا أَن يَشَاءَ اللَّهُ ۚ وَاذْكُر رَّبَّكَ إِذَا نَسِيتَ وَقُلْ عَسَىٰ أَن يَهْدِيَنِ رَبِّي لِأَقْرَبَ مِنْ هَٰذَا رَشَدًا (۲۴)(سورۃ الکہف)
Translation
And (O Prophet!) never say about any matter that I will do this tomorrow, (23) yes (say that) if Allah wills (I will do it), and whenever you forget, remember your Lord, and say: "I hope that my Lord will guide me to something that is even closer to guidance than this." (Asan Tarjuma-ul-Quran)
