Ibn Mas'ud reported God’s messenger as saying, “Make the <i>hajj</i> and the <i>‘umra</i> follow one another closely, for they remove poverty and sins as a blacksmith’s bellows remove impurities from iron, gold and silver; and a <i>hajja</i> which is accepted gets no less a reward than paradise." Tirmidhi and Nasa'i transmitted it, and Ahmad and Ibn Majah transmitted it from ‘Umar up to “from iron."

وَعَنِ ابْنِ مَسْعُودٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «تَابِعُوا بَيْنَ الْحَجِّ وَالْعُمْرَةِ فَإِنَّهُمَا يَنْفِيَانِ الْفَقْرَ وَالذُّنُوبَ كَمَا يَنْفِي الْكِيرُ خَبَثَ الْحَدِيدِ وَالذَّهَبِ وَالْفِضَّةِ وَلَيْسَ لِلْحَجَّةِ الْمَبْرُورَةِ ثَوَابٌ إِلَّا الْجَنَّةَ» . رَوَاهُ التِّرْمِذِيُّ وَالنَّسَائِيُّ وَرَوَاهُ أَحْمَدُ وَابْنُ مَاجَهْ عَنْ عُمَرَ إِلَى قَوْله: «خبث الْحَدِيد»
