Sunan Ibn Majah, Book 25, Hadith 2998 (In-Book) ⓘ
It was narrated from ‘Umar that the Prophet said: “Perform Hajj and ‘Umrah, one after the other, for performing them one after the other removes poverty and sin as the bellows removes impurity from iron.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَاصِمِ بْنِ عُبَيْدِ اللَّهِ، عَنْ عَبْدِ اللَّهِ بْنِ عَامِرٍ، عَنْ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " تَابِعُوا بَيْنَ الْحَجِّ وَالْعُمْرَةِ فَإِنَّ الْمُتَابَعَةَ بَيْنَهُمَا تَنْفِي الْفَقْرَ وَالذُّنُوبَ كَمَا يَنْفِي الْكِيرُ خَبَثَ الْحَدِيدِ " .
