All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
We invoke Allaah to bless your husband and help him to be keener on doing good deeds. It is recommended by Sharee‘ah to make ‘Umrah many times. This is evidenced by a Hadeeth on the authority of Abu Hurayrah that the Messenger of Allaah, sallallaahu ‘alayhi wa sallam, said, “One ‘Umrah after another expiate what is in between, and an accepted Hajj brings no less a reward than Paradise.” [Al-Jamaa‘ah except for Abu Daawood]
Ash-Shawkaani said, “The Hadeeth indicates the favorability of making ‘Umrah many times, contrary to the opinion of some scholars, such as the Maalikis, who maintain that it is disliked to perform ‘Umrah more than once in the same year and also contrary to the opinion of some other scholars who maintain that it is disliked to perform ‘Umrah more than once in the same month.”
In a Marfoo‘ Hadeeth on the authority of Ibn Mas‘ood the Messenger, sallallaahu ‘alayhi wa sallam, said, “Perform Hajj and ‘Umrah following each other , for they remove poverty and sins as the bellows removes the dross of iron and an accepted Hajj brings no less a reward than Paradise.” [Ath-Thahabi, Ibn Hajar, and Al-Albaani: Hasan]
As long as your husband gives much to charity, do not discourage him to make lots of ‘Umrah. Scholars stated that making Hajj and ‘Umrah as well is better than giving its costs in to charity unless it is for needy relatives or people who urgently need aid. In this case charity has the priority over ‘Umrah.
If your husband spends some of his money on other acts of worship that extend to others, such as supporting students to learn Sharee‘ah and schools that teach students the Quran, it would be better for him than doing such acts of worship whose benefit is restricted to him.
Hajj organizers make due arrangements to help prevent harms resulting from overcrowding, including controlling the number of pilgrims.
As for the contradiction that is seen in many people, it should be corrected by giving advice to the person involved. A person who neglects a certain aspect should be enjoined to do good and forbidden to do evil. He also should be reminded of the obligations to achieve balance, because all the Commands of Allaah The Almighty must be obeyed.
We supplicate Allaah to guide all Muslims to what is best for them and grant them success.
Allaah Knows best.
