Fasting

Bukhari :: Book 3 :: Volume 31 :: Hadith 126

Narrated Ibn 'Abbas:

The Prophet 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 used to meet him on every night of Ramadan till the end of the month. The Prophet used to recite the Holy Qur'an to Gabriel, and when Gabriel met him, he used to be more generous than a fast wind (which causes rain and welfare).
