Sunan an-Nasai
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 " .
It was narrated that 'Abdullah said: "The Messenger of Allah said: 'Perform Hajj and 'Umrah consecutively, for they remove poverty and sin as the bellows removes impurity from iron and gold and silver, and Hajj Al-Mabrur brings no less a reward than Paradise.'''
