Key Verses

1. 2:276Al-Baqarah
   يَمۡحَقُ ٱللَّهُ ٱلرِّبَوٰاْ وَيُرۡبِي ٱلصَّدَقَٰتِۗ وَٱللَّهُ لَا يُحِبُّ كُلَّ كَفَّارٍ أَثِيمٍ
   Allah hath blighted usury and made almsgiving fruitful. Allah loveth not the impious and guilty.
   In context

   Allah wipes out usury either by actually destroying it or by removing His blessing. Yet He increases charity and makes it grow by multiplying its reward by ten times up to seven hundred times or even more, and blesses those that give charity from their wealth. Allah does not love a stubborn disbeliever who considers the prohibited as lawful and persists in sins.

2. 13:17Ar-Rad
   أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءٗ فَسَالَتۡ أَوۡدِيَةُۢ بِقَدَرِهَا فَٱحۡتَمَلَ ٱلسَّيۡلُ زَبَدٗا رَّابِيٗاۖ وَمِمَّا يُوقِدُونَ عَلَيۡهِ فِي ٱلنَّارِ ٱبۡتِغَآءَ حِلۡيَةٍ أَوۡ مَتَٰعٖ زَبَدٞ مِّثۡلُهُۥۚ كَذَٰلِكَ يَضۡرِبُ ٱللَّهُ ٱلۡحَقَّ وَٱلۡبَٰطِلَۚ فَأَمَّا ٱلزَّبَدُ فَيَذۡهَبُ جُفَآءٗۖ وَأَمَّا مَا يَنفَعُ ٱلنَّاسَ فَيَمۡكُثُ فِي ٱلۡأَرۡضِۚ كَذَٰلِكَ يَضۡرِبُ ٱللَّهُ ٱلۡأَمۡثَالَ
   He sendeth down water from the sky, so that valleys flow according to their measure, and the flood beareth (on its surface) swelling foam - from that which they smelt in the fire in order to make ornaments and tools riseth a foam like unto it - thus Allah coineth (the similitude of) the true and the false. Then, as for the foam, it passeth away as scum upon the banks, while, as for that which is of use to mankind, it remaineth in the earth. Thus Allah coineth the similitudes.
   In context

   Allah strikes an example of the erosion of falsehood and the survival of truth with rainwater that comes down from the sky and causes riverbeds to flow, each according to its size, whether big or small. The overflowing water carries on its surface scum and froth that rise above the water.

3. 26:18Ash-Shuara
   قَالَ أَلَمۡ نُرَبِّكَ فِينَا وَلِيدٗا وَلَبِثۡتَ فِينَا مِنۡ عُمُرِكَ سِنِينَ
   (Pharaoh) said (unto Moses): Did we not rear thee among us as a child? And thou didst dwell many years of thy life among us,
   In context

   Pharaoh said to Moses (peace be upon him): Did we not bring you up as a child among us? Did you not stay with us for many years of your life? So what has now made you claim prophethood?

4. 30:39Ar-Rum
   وَمَآ ءَاتَيۡتُم مِّن رِّبٗا لِّيَرۡبُوَاْ فِيٓ أَمۡوَٰلِ ٱلنَّاسِ فَلَا يَرۡبُواْ عِندَ ٱللَّهِۖ وَمَآ ءَاتَيۡتُم مِّن زَكَوٰةٖ تُرِيدُونَ وَجۡهَ ٱللَّهِ فَأُوْلَـٰٓئِكَ هُمُ ٱلۡمُضۡعِفُونَ
   That which ye give in usury in order that it may increase on (other) people's property hath no increase with Allah; but that which ye give in charity, seeking Allah's Countenance, hath increase manifold.
   In context

   Whatever wealth you give to anyone with the expectation that they will.return it to you with an increase, that wealth does not grow with Allah. And whatever wealth you give to fulfil someone's need, desiring only the pleasure of Allah, and not praise or reward from the people, the reward of that deed shall be multiplied for you by Allah.
