حَدَّثَنَا ابْنُ نُمَيْرٍ حَدَّثَنَا الْعَلَاءُ بْنُ صَالِحٍ حَدَّثَنَا الْمِنْهَالُ بْنُ عَمْرٍو عَنْ سَعِيدِ بْنِ جُبَيْرٍ أَنَّ رَجُلًا أَتَى ابْنَ عَبَّاسٍ فَقَالَ أُنْزِلَ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَشْرًا بِمَكَّةَ وَعَشْرًا بِالْمَدِينَةِ فَقَالَ مَنْ يَقُولُ ذَلِكَ لَقَدْ أُنْزِلَ عَلَيْهِ بِمَكَّةَ عَشْرًا وَخَمْسًا وَسِتِّينَ وَأَكْثَرَ
مسند امام احمد بن حنبل · Hadith 2035
It was narrated from Sa'eed bin Jubair that a man came to Ibn 'Abbas and said: The Prophet (PBUH)received Revelation for ten years in Makkah and ten years in Madinah. He said: Who is saying that? He received Revelation in Makkah for fifteen years and in Madinah for ten years and sixty-five days or more.
