Focus and concentration

حَـٰفِظُوا۟ عَلَى ٱلصَّلَوَٰتِ وَٱلصَّلَوٰةِ ٱلْوُسْطَىٰ وَقُومُوا۟ لِلَّهِ قَـٰنِتِينَ

Maintain with care the [obligatory] prayers and [in particular] the middle [i.e., ʿaṣr] prayer and stand before Allāh, devoutly obedient.

وَإِذَا قُرِئَ ٱلْقُرْءَانُ فَٱسْتَمِعُوا۟ لَهُۥ وَأَنصِتُوا۟ لَعَلَّكُمْ تُرْحَمُونَ

So when the Qur’ān is recited, then listen to it and pay attention that you may receive mercy.

إِنَّ نَاشِئَةَ ٱلَّيْلِ هِىَ أَشَدُّ وَطْـًٔا وَأَقْوَمُ قِيلًا

Indeed, the hours of the night are more effective for concurrence [of heart and tongue] and more suitable for words.
