Hazrat Ibn Mas’ood R.A. relates that Rasulullah Sal’am said: ‘Follow up the Haj or the unrah (with each other) for verily they remove poverty and sin in the same manner that fire cleans away the dirt in iron, gold and silver’.
Here one is encouraged to follow up Haj and umrah with each other. The meaning of ‘follow up’ can be explained thus: Among the three manners of performing Haj, is Quraan; which according to the Hanafi is the most virtuous form of Haj. This is the manner in which the Holy Prophet Sal’am put on his ihraam with the niyyat of performing both Haj and umrah with the same ihraam all in one.
Secondly, ‘follow up’ may also mean that when you have performed Haj, you should also perform umrah afterwards and vice versa. You should follow up the one with the other. One Hadith states that: ‘Follow up between Haj and Umrah which increase one lifespan and removes poverty and sins as fire removes dirt’. (Targheeb)
Another Hadith states: ‘Continue to perform Haj and umrah for Allah’s sake forever, for these two clean away poverty and sin as fire removes dirt from iron’. (Kanz)
‘Performing Haj and umrah often stops poverty.’ (Kanz) ‘Continuous performing of Haj an umrah removes poverty and sin just as fire removes dirt from iron’. (Kanz) ‘Following up between Haj and umrah increases one’s life span and increases one’s sustenance’. (Kanz).
The same theme runs through many other ahaadith. Hazrat Imaam Nawawi R.A. has stated that the performing of umrah in abundance is mustahab. Hazrat Imaam Ibn Hajar Makki R.A. quoted Hazrat Imaam Shafi’ee R.A. as saying that where one is able, one should not allow any month to pass by without performing at least one umrah; and if one performs two or three, so much better.
