quran:40:55 –

So be patient, ˹O Muhammad˺. Indeed, the promise of Allah is truth. And ask forgiveness for your sin and exalt ˹Allah˺ with praise of your Lord in the evening and the morning.  

So be patient, O Muhammad (s). Surely God’s promise, to grant victory to His friends, is true — for you and whoever follows you are among such ˹friends˺. And ask forgiveness for your sin, so that you will be emulated in this ˹by your community˺, and glorify, perform prayer, continuously, with praise of your Lord at night — which means after sunset — and in the early hours: the five prayers.
القرآن:٤٠:٥٥ –

فَاصْبِرْ إِنَّ وَعْدَ اللَّهِ حَقٌّ وَاسْتَغْفِرْ لِذَنْبِكَ وَسَبِّحْ بِحَمْدِ رَبِّكَ بِالْعَشِيِّ وَالْإِبْكَارِ  

{فاصبر} يا محمد {إن وعد الله} بنصر أوليائه {حق} وأنت ومن تبعك منهم {واستغفر لذنبك} ليستن بك {وسبِّح} صل متلبساً {بحمد ربك بالعشي} وهو من بعد الزوال {والإبكار} الصلوات الخمس.
