Sura al-Nūr 24:37

رِجَالٌ لَّا تُلْهِيهِمْ تِجَٰرَةٌ وَلَا بَيْعٌ عَن ذِكْرِ ٱللَّـهِ وَإِقَامِ ٱلصَّلَوٰةِ وَإِيتَآءِ ٱلزَّكَوٰةِ يَخَافُونَ يَوْمًا تَتَقَلَّبُ فِيهِ ٱلْقُلُوبُ وَٱلْأَبْصَٰرُ

rijālun lā tulhīhim tijāratun wa-lā bayʿun ʿan dhikri allāhi wa-iqāmi l-ṣalawti wa-ītāʾi l-zakawti yakhāfūna yawman tataqallabu fīhi l-qulūbu wa-l-abṣāru

By men whom neither traffic nor merchandise can divert from the Remembrance of Allah, nor from regular Prayer, nor from the practice of regular Charity: Their (only) fear is for the Day when hearts and eyes will be transformed (in a world wholly new),-

Sura al-Nūr 24:44

يُقَلِّبُ ٱللَّـهُ ٱلَّيْلَ وَٱلنَّهَارَ إِنَّ فِى ذَٰلِكَ لَعِبْرَةً لِّأُو۟لِى ٱلْأَبْصَٰرِ

yuqallibu allāhu l-layla wa-l-nahāra inna fī dhālika la-ʿibratan li-lūlī l-abṣāri

It is Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision!

Sura al-Nūr 24:50

أَفِى قُلُوبِهِم مَّرَضٌ أَمِ ٱرْتَابُوٓا۟ أَمْ يَخَافُونَ أَن يَحِيفَ ٱللَّـهُ عَلَيْهِمْ وَرَسُولُهُۥ بَلْ أُو۟لَٰٓئِكَ هُمُ ٱلظَّٰلِمُونَ

afī qulūbihim maraḍun ami irtābū am yakhāfūna an yaḥīfa allāhu ʿalayhim wa-rasūluhu bal ulāʾika humu l-ẓālimūna

Is it that there is a disease in their hearts? or do they doubt, or are they in fear, that Allah and His Messenger will deal unjustly with them? Nay, it is they themselves who do wrong.
