Ghafir 40:55

Fasbir inna waAAda Allahihaqqun wastaghfir lithanbika wasabbihbihamdi rabbika bilAAashiyyi wal-ibkar

So be patient, [O Muḥammad]. Indeed, the promise of Allāh is truth. And ask forgiveness for your sin and exalt [Allāh] with praise of your Lord in the evening and the morning.

So, be patient - surely the promise of Allah is true - and seek forgiveness for your sins, and proclaim the purity and praise of your Lord in the afternoon and at dawn.
