أَخْبَرَنَا أَبُو دَاوُدَ، قَالَ حَدَّثَنَا أَبُو عَتَّابٍ، قَالَ حَدَّثَنَا عَزْرَةُ بْنُ ثَابِتٍ، عَنْ عَمْرِو بْنِ دِينَارٍ، قَالَ قَالَ ابْنُ عَبَّاسٍ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تَابِعُوا بَيْنَ الْحَجِّ وَالْعُمْرَةِ فَإِنَّهُمَا يَنْفِيَانِ الْفَقْرَ وَالذُّنُوبَ كَمَا يَنْفِي الْكِيرُ خَبَثَ الْحَدِيدِ " .
Ibn 'abbas said: "The Messenger of Allah said: 'Perform Hajj and 'Umrah consecutively; for they remove poverty and sin as the bellows removes impurity from iron.'''
