Surah Az-Zumar (The Successive Groups), Verse 9

اَمَّنْ هُوَ قَانِتٌ اٰنَآءَ الَّیْلِ سَاجِدًا وَّقَآىِٕمًا یَّحْذَرُ الْاٰخِرَةَ وَیَرْجُوْا رَحْمَةَ رَبِّهٖ قُلْ هَلْ یَسْتَوِی الَّذِیْنَ یَعْلَمُوْنَ وَالَّذِیْنَ لَا یَعْلَمُوْنَ اِنَّمَا یَتَذَكَّرُ اُولُوا الْاَلْبَابِ 

Amman huwa qaanitun aanaaa'al laili saajidanw wa qaaa'imai yahzarul Aakhirata wa yarjoo rahmata Rabbih; qul hal yastawil lazeena ya'lamoona wallazeena laa ya'lamoon; innamaa yatazakkaru ulul albaab

“Is one who worships devoutly during the hour of the night prostrating himself or standing (in adoration), who takes heed of the Hereafter, and who places his hope in the Mercy of his Lord - (like one who does not)? Say: "Are those equal, those who know and those who do not know? It is those who are endued with understanding that receive admonition.”
