﴿ إِنَّ نَاشِئَةَ ٱلَّيْلِ هِىَ أَشَدُّ وَطْـًۭٔا وَأَقْوَمُ قِيلًا ﴾

“[and,] verily, the hours of night the mind most strongly and speak with the clearest voice,”

(Lo! the vigil of the night) spent in praying (is (a time) when impression is more keen) the vigil of the night and praying at this time give a person more vigour in his prayer, when he seeks by it Allah's sake alone; it is also said this means: it is gentler and milder on the heart (and speech more certain) the recitation of the Qur'an is clearer and firmer.
