Sincerity and Intention (Niyyah)

وَمِنَ ٱلنَّاسِ مَن يَقُولُ ءَامَنَّا بِٱللَّهِ وَبِٱلْيَوْمِ ٱلْـَٔاخِرِ وَمَا هُم بِمُؤْمِنِينَ

And of the people are some who say, "We believe in Allāh and the Last Day," but they are not believers.

قُلْ أَنفِقُوا۟ طَوْعًا أَوْ كَرْهًا لَّن يُتَقَبَّلَ مِنكُمْ ۖ إِنَّكُمْ كُنتُمْ قَوْمًا فَـٰسِقِينَ

Say, "Spend willingly or unwillingly; never will it be accepted from you. Indeed, you have been a defiantly disobedient people."

وَمِنَ ٱلْأَعْرَابِ مَن يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَيَتَّخِذُ مَا يُنفِقُ قُرُبَـٰتٍ عِندَ ٱللَّهِ وَصَلَوَٰتِ ٱلرَّسُولِ ۚ أَلَآ إِنَّهَا قُرْبَةٌ لَّهُمْ ۚ سَيُدْخِلُهُمُ ٱللَّهُ فِى رَحْمَتِهِۦٓ ۗ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ

But among the bedouins are some who believe in Allāh and the Last Day and consider what they spend as means of nearness to Allāh and of [obtaining] invocations of the Messenger. Unquestionably, it is a means of nearness for them. Allāh will admit them to His mercy. Indeed, Allāh is Forgiving and Merciful.

لَن يَنَالَ ٱللَّهَ لُحُومُهَا وَلَا دِمَآؤُهَا وَلَـٰكِن يَنَالُهُ ٱلتَّقْوَىٰ مِنكُمْ ۚ كَذَٰلِكَ سَخَّرَهَا لَكُمْ لِتُكَبِّرُوا۟ ٱللَّهَ عَلَىٰ مَا هَدَىٰكُمْ ۗ وَبَشِّرِ ٱلْمُحْسِنِينَ

Their meat will not reach Allāh, nor will their blood, but what reaches Him is piety from you. Thus have We subjected them to you that you may glorify Allāh for that [to] which He has guided you; and give good tidings to the doers of good.

۞ قَالَتِ ٱلْأَعْرَابُ ءَامَنَّا ۖ قُل لَّمْ تُؤْمِنُوا۟ وَلَـٰكِن قُولُوٓا۟ أَسْلَمْنَا وَلَمَّا يَدْخُلِ ٱلْإِيمَـٰنُ فِى قُلُوبِكُمْ ۖ وَإِن تُطِيعُوا۟ ٱللَّهَ وَرَسُولَهُۥ لَا يَلِتْكُم مِّنْ أَعْمَـٰلِكُمْ شَيْـًٔا ۚ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ

The bedouins say, "We have believed." Say, "You have not [yet] believed; but say [instead], 'We have submitted,' for faith has not yet entered your hearts. And if you obey Allāh and His Messenger, He will not deprive you from your deeds of anything. Indeed, Allāh is Forgiving and Merciful."
