Qur'an 39:9

أَمَّنْ هُوَ قَـٰنِتٌ ءَانَآءَ ٱلَّيْلِ سَاجِدًا وَقَآئِمًا يَحْذَرُ ٱلْـَٔاخِرَةَ وَيَرْجُوا۟ رَحْمَةَ رَبِّهِۦ ۗ قُلْ هَلْ يَسْتَوِى ٱلَّذِينَ يَعْلَمُونَ وَٱلَّذِينَ لَا يَعْلَمُونَ ۗ إِنَّمَا يَتَذَكَّرُ أُو۟لُوا۟ ٱلْأَلْبَـٰبِ

Is he who payeth adoration in the watches of the night, prostrate and standing, bewaring of the Hereafter and hoping for the mercy of his Lord, (to be accounted equal with a disbeliever)? Say (unto them, O Muhammad): Are those who know equal with those who know not? But only men of understanding will pay heed.
