Hazrat Abdullah ibn Abbas (may Allah be pleased with them both) narrated that the Prophet (peace and blessings of Allah be upon him) was the most generous amongst the people, and he used to be more so in the month of Ramadan when Gabriel visited him, and Gabriel (peace be upon him) used to meet him on every night of Ramadan till the end of the month. The Prophet (peace and blessings of Allah be upon him) used to recite the Holy Qur’an to Gabriel (peace be upon him), and when Gabriel (peace be upon him) met him, he used to be more generous than a fast wind (which causes rain and welfare).
