إِنَّ ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ وَأَقَامُوا۟ ٱلصَّلَوٰةَ وَءَاتَوُا۟ ٱلزَّكَوٰةَ لَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
See 2:4.
Commentary:
The verse points out that abstaining from interest and giving money in charity are highly righteous deeds and the righteous will have their reward with God. The verse also declares that in order to attain salvation (1) one must have true faith, and (2) do righteous deeds; and of the righteous deeds the verse singles out the two most important ones: firstly, the observance of Prayers, which pertains to the rights of God; and secondly, the giving of Zakah which pertains to the rights of men. The noble spirit underlying the commandment relating to Zakah runs counter to the evil spirit underlying the practice of giving and taking interest.
