Surah Ar Rum Tafseer

وَمَا اتَيْتُم مِّن رِّبًا لِّيَرْبُوَ فِي أَمْوَالِ النَّاسِ فَلَ يَرْبُو عِندَ اللَّهِ

And that which you give in Riba, in order that it may increase from other people's property, has no increase with Allah;

This means, that which is given as a gift to others in the hope that they will give back more than they were given. There is no reward for this with Allah.

This is how this Ayah was interpreted by Ibn Abbas, Mujahid, Ad-Dahhak, Qatadah, Ikrimah, Muhammad bin Ka`b and Ash-Sha`bi.

Allah says:

وَمَا اتَيْتُم مِّن زَكَاةٍ تُرِيدُونَ وَجْهَ اللَّهِ فَأُوْلَيِكَ هُمُ الْمُضْعِفُونَ

but that which you give in Zakah seeking Allah's Face, then those they shall have manifold increase.

Those are the ones for whom Allah will multiply the reward.

It was reported in the Sahih:

وَمَا تَصَدَّقَ أَحَدٌ بِعَدْلِ تَمْرَةٍ مِنْ كَسْبٍ طَيِّبٍ إِلاَّ أَخَذَهَا الرَّحْمَنُ بِيَمِينِهِ فَيُرَبِّيهَا لِصَاحِبِهَا كَمَا يُرَبِّي أَحَدُكُمْ فَلُوَّهُ أَوْ فَصِيلَهُ حَتَّى تَصِيرَ التَّمْرَةُ أَعْظَمَ مِنْ أُحُد

No person gives in charity the equivalent of a date which was earned in a lawful manner, but the Most Merciful takes it in His Right Hand and takes care of it for its owner, just as any one of you takes care of his foal or young camel, until the date becomes the size of Mount Uhud.

Creation, Provision, Life and Death are all in the Hand of Allah

Allah says
