(Imam Bukhari said:) Abdan narrated to us, he said: Abdullah informed us, he said: Yunus informed us, from Zuhri. (Another chain) (Imam Bukhari said:) Bishr bin Muhammad narrated to us, he said: Abdullah informed us, he said: Yunus and Ma'mar informed us likewise, from Zuhri, he said: Ubaidullah bin Abdullah informed me, from Hazrat Ibn Abbas (may Allah be pleased with both of them), he narrates that:
The Messenger of Allah ﷺ was the most generous of all people, and he was most generous in Ramadan, when Hazrat Jibril would meet him. Hazrat Jibril would meet him every night of Ramadan and would revise the Noble Qur'an with him, so the Messenger of Allah ﷺ was more generous in goodness than the sent winds (for the benefit of people).
حَدَّثَنَا عَبْدَانُ ، قَالَ: أَخْبَرَنَا عَبْدُ اللهِ ، قَالَ: أَخْبَرَنَا يُونُسُ ، عَنِ الزُّهْرِيِّ (ح). وَحَدَّثَنَا بِشْرُ بْنُ مُحَمَّدٍ ، قَالَ: أَخْبَرَنَا عَبْدُ اللهِ ، قَالَ: أَخْبَرَنَا يُونُسُ وَمَعْمَرٌ ، عَنِ الزُّهْرِيِّ نَحْوَهُ، قَالَ: أَخْبَرَنِي عُبَيْدُ اللهِ بْنُ عَبْدِ اللهِ، عَنِ ابْنِ عَبَّاسٍ ، قَالَ
كَانَ رَسُولُ اللهِ ﷺ أَجْوَدَ النَّاسِ، وَكَانَ أَجْوَدُ مَا يَكُونُ فِي رَمَضَانَ حِينَ يَلْقَاهُ جِبْرِيلُ، وَكَانَ يَلْقَاهُ فِي كُلِّ لَيْلَةٍ مِنْ رَمَضَانَ فَيُدَارِسُهُ الْقُرْآنَ، فَلَرَسُولُ اللهِ ﷺ أَجْوَدُ بِالْخَيْرِ مِنَ الرِّيحِ الْمُرْسَلَةِ.
