Surah Ghafir — Ayah 44 (40:44)
فَسَتَذۡكُرُونَ مَآ أَقُولُ لَكُمۡۚ وَأُفَوِّضُ أَمۡرِيٓ إِلَى ٱللَّهِۚ إِنَّ ٱللَّهَ بَصِيرُۢ بِٱلۡعِبَادِ ٤٤
English translation (Saheeh International)
And you will remember what I [now] say to you, and I entrust my affair to Allāh. Indeed, Allāh is Seeing of [His] servants."
Brief commentary
But they rejected his advice, and so he said: “You will remember the advice I gave you and you will regret not accepting it. And I entrust all my affairs over to Allah alone. Allah is Seeing of His servants; nothing of their actions is hidden from Him”.
