The Messenger of Allah said: "Alternate between Hajj and Umrah; for those two remove poverty and sins just as the bellows removes filth from iron, gold, and silver - and there is no reward for Al-Hajj Al-Mabrur except for Paradise."  

قَالَ رَسُولُ اللَّهِ ﷺ تَابِعُوا بَيْنَ الْحَجِّ وَالْعُمْرَةِ فَإِنَّهُمَا يَنْفِيَانِ الْفَقْرَ وَالذُّنُوبَ كَمَا يَنْفِي الْكِيرُ خَبَثَ الْحَدِيدِ وَالذَّهَبِ وَالْفِضَّةِ وَلَيْسَ لِلْحَجَّةِ الْمَبْرُورَةِ ثَوَابٌ إِلاَّ الْجَنَّةُ قَالَ وَفِي الْبَابِ عَنْ عُمَرَ وَعَامِرِ بْنِ رَبِيعَةَ وَأَبِي هُرَيْرَةَ وَعَبْدِ اللَّهِ بْنِ حُبْشِيٍّ وَأُمِّ سَلَمَةَ وَجَابِرٍ  

The Messenger of Allah said: "Whoever performs Hajj for Allah, and he does not have sexual relations nor commit any sin, then his previous sins will be forgiven."  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ حَجَّ فَلَمْ يَرْفُثْ وَلَمْ يَفْسُقْ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
