So give the relative his right, as well as the needy and the traveler. That is best for those who desire the countenance of Allah, and it is they who will be the successful.  

فَآتِ ذَا الْقُرْبَىٰ حَقَّهُ وَالْمِسْكِينَ وَابْنَ السَّبِيلِ ۚ ذَٰلِكَ خَيْرٌ لِلَّذِينَ يُرِيدُونَ وَجْهَ اللَّهِ ۖ وَأُولَٰئِكَ هُمُ الْمُفْلِحُونَ  

And whatever you give for interest to increase within the wealth of people will not increase with Allah. But what you give in zakah, desiring the countenance of Allah - those are the multipliers.  

وَمَا آتَيْتُمْ مِنْ رِبًا لِيَرْبُوَ فِي أَمْوَالِ النَّاسِ فَلَا يَرْبُو عِنْدَ اللَّهِ ۖ وَمَا آتَيْتُمْ مِنْ زَكَاةٍ تُرِيدُونَ وَجْهَ اللَّهِ فَأُولَٰئِكَ هُمُ الْمُضْعِفُونَ  

Allah is the one who created you, then provided for you, then will cause you to die, and then will give you life. Are there any of your "partners" who does anything of that? Exalted is He and high above what they associate with Him.  

اللَّهُ الَّذِي خَلَقَكُمْ ثُمَّ رَزَقَكُمْ ثُمَّ يُمِيتُكُمْ ثُمَّ يُحْيِيكُمْ ۖ هَلْ مِنْ شُرَكَائِكُمْ مَنْ يَفْعَلُ مِنْ ذَٰلِكُمْ مِنْ شَيْءٍ ۚ سُبْحَانَهُ وَتَعَالَىٰ عَمَّا يُشْرِكُونَ
