Insha Allah

Surah Al-Kahf, Verse 23:

وَلَا تَقُولَنَّ لِشَيْءٍ إِنِّي فَاعِلٌ ذَٰلِكَ غَدًا

And do not say of anything: Surely I will do it tomorrow,

Surah Al-Kahf, Verse 24:

إِلَّا أَن يَشَاءَ اللَّهُ وَاذْكُر رَّبَّكَ إِذَا نَسِيتَ وَقُلْ عَسَىٰ أَن يَهْدِيَنِ رَبِّي لِأَقْرَبَ مِنْ هَٰذَا رَشَدًا

Unless Allah pleases; and remember your Lord when you forget and say: Maybe my Lord will guide me to a nearer course to the right than this.
