from the Prophet ﷺ- that he said: ʿFollow Hajj with ‘Umrah and 'Umrah with Hajj, for doing that will eliminate poverty and sin as the bellows eliminate dross.ʿ (Using translation from Aḥmad 167)
النَّبِيِّ ﷺ قَالَ تَابِعُوا بَيْنَ الْحَجِّ وَالْعُمْرَةِ فَإِنَّ مُتَابَعَةً بَيْنَهُمَا يَنْفِيَانِ الذُّنُوبَ وَالْفَقْرَ كَمَا يَنْفِي الْكِيرُ الْخَبَثَ قَالَ سُفْيَانُ لَيْسَ فِيهِ أَبُوهُ وَيَزِيدُ فِي الْعُمُرِ مَائَةَ مَرَّةٍ
