Surah Taha 20:44

فَقُولَا لَهُۥ قَوْلًا لَّيِّنًا لَّعَلَّهُۥ يَتَذَكَّرُ أَوْ يَخْشَىٰ

And speak to him with gentle speech that perhaps he may be reminded or fear [Allāh]."

Translation: Saheeh International

Tafsir

And speak to him gentle words for him to renounce such claims that perhaps he may be mindful be admonished or fear’ God and so repent — the ‘hope’ for Pharaoh’s repentance is expressed from their perspective for God knows that he was not going to repent.
