Reward for the Charitable, the True Believers and the Martyrs; and the Destination of the Disbelieve

Allah the Exalted describes the reward that He will award to those who spend from their wealth, whether male or female, on the needy, the poor and the meek,

اللَّهَ قَرْضاً حَسَناً وَمَا

أَلَمْ يَأْنِ لِلَّذِينَ آمَنُوا أَن تَخْشَعَ قُلُوبُهُمْ لِذِكْرِ‌ اللَّـهِ وَمَا نَزَلَ مِنَ الْحَقِّ (Has the time not yet come for those who believe that their hearts should be humble for the remembrance of Allah and for the truth that has descended [ through revelation ]?...57:16) The phrase khushu'-ul-qalb means 'for the heart to soften; to be receptive to advice; to be obedient; to submit'. [ Ibn Kathir ] In the Qur'anic context, it implies 'a complete willingness to yield to the Divine injunctions, or the Divine imperatives and prohibitions without allowing any laxity in following them. [ Ruh-ul-Ma’ ani ]

This verse admonishes the believers. Sayyidna ` Abdullah Ibn ` Abbas ؓ reports that some of the believers were found to be lacking in firmness, and somewhat laziness was felt in their practices. So this verse was revealed. Imam A'mash (رح) said: After settling down in Madinah, the blessed Companions ؓ experienced socio-economic comfort and prosperity; as a result some of them relaxed in exerting their efforts to do good works as they used to do previously. Thus this verse was revealed. [ Ruh-ul-Ma’ ani ]
