أَخْبَرَنَا مُحَمَّدُ بْنُ كَثِيرٍ ، عَنْ الْأَوْزَاعِيِّ ، عَنْ حَسَّانَ ، قَالَ :" كَانَ جِبْرِيلُ يَنْزِلُ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالسُّنَّةِ كَمَا يَنْزِلُ عَلَيْهِ بِالْقُرْآنِ "

Muhammad ibn Kathir told us, on the authority of Al-Awza’i, on the authority of Hassan, who said: “Gabriel used to descend upon the Prophet, may God’s prayers and peace be upon him, according to the Sunnah, as sent down to him the Qur’an.”
