"The Messenger of Allah was the most generous of people, and he was most generous in Ramadan when Jibril met him. Jibril use to meet him every night during the month of Ramadan and study Quran with him." And he said: "When Jibril met him, the Messenger of Allah was more generous in doing good than the blowing wind."

Sunan an-Nasa'i Book 22, Hadith 6
