الترمذي:٨١٧حَدَّثَنَا ابْنُ أَبِي عُمَرَ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ قَالَ

لَمَّا أَرَادَ النَّبِيُّ ﷺ الْحَجَّ أَذَّنَ فِي النَّاسِ فَاجْتَمَعُوا فَلَمَّا أَتَى الْبَيْدَاءَ أَحْرَمَ  

قَالَ وَفِي الْبَابِ عَنِ ابْنِ عُمَرَ وَأَنَسٍ وَالْمِسْوَرِ بْنِ مَخْرَمَةَ قَالَ أَبُو عِيسَى حَدِيثُ جَابِرٍ حَدِيثٌ حَسَنٌ صَحِيحٌ
