مُسْنَدُ أَحْمَدَ
Musnad Ahmad 2041
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn 'Abbas said: The Messenger of Allah (ﷺ) used to review the Qur'an with Jibreel (عليه السلام) every Ramadan, and the morning after the night in which he reviewed it, he would be more generous than the blowing wind; he was not asked for anything but he gave it. In the month (of Ramadan) after which he died, he reviewed it with him twice.
