warning against hypocrisy

إِنَّ ٱللَّهَ لَا يَخْفَىٰ عَلَيْهِ شَىْءٌ فِى ٱلْأَرْضِ وَلَا فِى ٱلسَّمَآءِ

Indeed, from Allāh nothing is hidden in the earth nor in the heaven.

۞ أَجَعَلْتُمْ سِقَايَةَ ٱلْحَآجِّ وَعِمَارَةَ ٱلْمَسْجِدِ ٱلْحَرَامِ كَمَنْ ءَامَنَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَجَـٰهَدَ فِى سَبِيلِ ٱللَّهِ ۚ لَا يَسْتَوُۥنَ عِندَ ٱللَّهِ ۗ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّـٰلِمِينَ

Have you made the providing of water for the pilgrim and the maintenance of al-Masjid al-Ḥarām equal to [the deeds of] one who believes in Allāh and the Last Day and strives in the cause of Allāh? They are not equal in the sight of Allāh. And Allāh does not guide the wrongdoing people.

وَرَبُّكَ يَعْلَمُ مَا تُكِنُّ صُدُورُهُمْ وَمَا يُعْلِنُونَ

And your Lord knows what their breasts conceal and what they declare.

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا تَنَـٰجَيْتُمْ فَلَا تَتَنَـٰجَوْا۟ بِٱلْإِثْمِ وَٱلْعُدْوَٰنِ وَمَعْصِيَتِ ٱلرَّسُولِ وَتَنَـٰجَوْا۟ بِٱلْبِرِّ وَٱلتَّقْوَىٰ ۖ وَٱتَّقُوا۟ ٱللَّهَ ٱلَّذِىٓ إِلَيْهِ تُحْشَرُونَ

O you who have believed, when you converse privately, do not converse about sin and aggression and disobedience to the Messenger but converse about righteousness and piety. And fear Allāh, to whom you will be gathered.
