Sincerity of Intention (Niyyah)

وَلِلَّهِ ٱلْمَشْرِقُ وَٱلْمَغْرِبُ ۚ فَأَيْنَمَا تُوَلُّوا۟ فَثَمَّ وَجْهُ ٱللَّهِ ۚ إِنَّ ٱللَّهَ وَٰسِعٌ عَلِيمٌ

And to Allāh belongs the east and the west. So wherever you [might] turn, there is the Face of Allāh. Indeed, Allāh is all-Encompassing and Knowing.

مَّن كَانَ يُرِيدُ ثَوَابَ ٱلدُّنْيَا فَعِندَ ٱللَّهِ ثَوَابُ ٱلدُّنْيَا وَٱلْـَٔاخِرَةِ ۚ وَكَانَ ٱللَّهُ سَمِيعًۢا بَصِيرًا

Whoever desires the reward of this world - then with Allāh is the reward of this world and the Hereafter. And ever is Allāh Hearing and Seeing.

وَمَا مَنَعَهُمْ أَن تُقْبَلَ مِنْهُمْ نَفَقَـٰتُهُمْ إِلَّآ أَنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَبِرَسُولِهِۦ وَلَا يَأْتُونَ ٱلصَّلَوٰةَ إِلَّا وَهُمْ كُسَالَىٰ وَلَا يُنفِقُونَ إِلَّا وَهُمْ كَـٰرِهُونَ

And what prevents their expenditures from being accepted from them but that they have disbelieved in Allāh and in His Messenger and that they come not to prayer except while they are lazy and that they do not spend except while they are unwilling.

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نَـٰجَيْتُمُ ٱلرَّسُولَ فَقَدِّمُوا۟ بَيْنَ يَدَىْ نَجْوَىٰكُمْ صَدَقَةً ۚ ذَٰلِكَ خَيْرٌ لَّكُمْ وَأَطْهَرُ ۚ فَإِن لَّمْ تَجِدُوا۟ فَإِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ

O you who have believed, when you [wish to] privately consult the Messenger, present before your consultation a charity. That is better for you and purer. But if you find not [the means] - then indeed, Allāh is Forgiving and Merciful.

إِلَّا ٱبْتِغَآءَ وَجْهِ رَبِّهِ ٱلْأَعْلَىٰ

But only seeking the face [i.e., acceptance] of his Lord, Most High.
