Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) was the most generous of all people, and when he met Sayyiduna Jibril (peace be upon him) in Ramadan he (peace and blessings be upon him) would be exceedingly generous. Sayyiduna Jibril (peace be upon him) would meet him every night of Ramadan until it (the month) ended, and the Prophet (peace and blessings be upon him) would recite the Qur'an to him. When Sayyiduna Jibril (peace be upon him) met him (peace and blessings be upon him), he (peace and blessings be upon him) would be more generous than the swift wind.
