Hadith 1222
Ibn 'Abbas (May Allah be pleased with them) reported:
وعن ابن عباس رضي الله عنهما: قال: كان رسول الله صلى الله عليه وسلم أجود الناس، وكان أجود ما يكون في رمضان حين يلقاه جبريل وكان جبريل يلقاه في كل ليلة من رمضان فيدارسه القرآن فَلَرَسول الله صلى الله عليه وسلم حين يلقاه جبريل أجود بالخير من الريح المرسلة" . ((متفق عليه))
The Messenger of Allah (ﷺ) was the most generous of the men; and he was the most generous during the month of Ramadan when Jibril visited him every night and recited the Qur'an to him. During this period, the generosity of Messenger of Allah (ﷺ) waxed faster than the rain bearing wind. [Al-Bukhari and Muslim].
In plain words
The Prophet was generous always, but most generous in Ramadan when the Qur'an was reviewed with him each night, his giving compared to a wind bringing rain to all. Nearness to the Qur'an opens the heart toward people.
