أَخْبَرَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ أَيُّوبَ، قَالَ حَدَّثَنَا سُلَيْمَانُ بْنُ حَيَّانَ أَبُو خَالِدٍ، عَنْ عَمْرِو بْنِ قَيْسٍ، عَنْ عَاصِمٍ، عَنْ شَقِيقٍ، عَنْ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تَابِعُوا بَيْنَ الْحَجِّ وَالْعُمْرَةِ فَإِنَّهُمَا يَنْفِيَانِ الْفَقْرَ وَالذُّنُوبَ كَمَا يَنْفِي الْكِيرُ خَبَثَ الْحَدِيدِ وَالذَّهَبِ وَالْفِضَّةِ وَلَيْسَ لِلْحَجِّ الْمَبْرُورِ ثَوَابٌ دُونَ الْجَنَّةِ " .
