Silsilah as-Sahihah 3940 — Reward for charity and loans

It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A man entered Paradise and saw that on one of its doors (this inscription) was written: The reward of charity is tenfold, and the reward of a loan is eighteenfold."
