Performing Hac multiple times is a virtuous act that carries immense reward. Hz. Peygamber (sallallahu aleyhi ve sellem) encouraged alternating between Hac and Umre, stating that they remove poverty and sins. He also described the reward of Hac mabrur as nothing less than Paradise. There is no doubt that repeating Hac is a praiseworthy act of worship.
Sheikh Ibn Baz stated that voluntary Hac is among the best acts of worship and is highly sunnet for those who have the means. He encouraged Muslims who have completed their farz Hac to return for additional Hac whenever possible. Each Hac is an opportunity for spiritual renewal, forgiveness, and drawing closer to Allah.
However, some scholars, including Sheikh Ibn Uthaymeen, discussed the question of priorities when the Muslim community has pressing needs. He noted that in situations where Muslims around the world are suffering from poverty, hunger, or conflict, spending the money on charity — feeding the hungry, helping refugees, building wells, or supporting education — may be more beneficial than a person's fifth or tenth voluntary Hac. He emphasized that this is a matter of context and individual assessment, not a blanket ruling. For a person whose heart is attached to the Kabe and whose worship is strengthened by repeated Hac, the spiritual benefit of voluntary Hac may be greater. The key is sincerity and wisdom in choosing how to spend one's wealth in the way most pleasing to Allah.
