Narrated Ibn Abbas:
Allah’s Messenger (peace be upon him) was the most generous of all the people, and he used to reach the peak in generosity in the month of Ramadan when Gabriel met him. Gabriel used to meet him every night of Ramadan to teach him the Qur’an. Allah’s Messenger was the most generous person, even more generous than the strong uncontrollable wind (in readiness and haste to do charitable deeds).
(Bukhari Vol. 1, Book 1, Hadith 5)
