Praise be to Allaah.
Take the whole amount, capital and profit, then keep the capital, because that is yours, and give the profit in charity, because it is ribaa. Allaah will make you independent by His bounty and will compensate you with something better, and He will help you to meet your need.
Whoever fears Allaah and keeps his duty to Him, He will make a way for him to get out (from every difficulty). And He will provide him from (sources) he never could imagine. And whosoever puts his trust in Allaah, then He will suffice him (cf. Al-Talaaq 65:2-3 – interpretation of the meaning).
And Allaah is the Source of strength. May Allaah bless our Prophet Muhammad and his family and companions, and grant them peace.
