What is better for a Muslim after the obligatory Hajj: to repeat Hajj voluntarily or to give charity with the money?

The fundamental principle is that voluntary Hajj (pilgrimage) is superior to charity. However, charity may be superior if it is given to people in dire need, especially if they are relatives, or if it is for the sake of Jihad and calling to Allah. Hajj is a physical and financial act of worship that is superior to non-obligatory charity, provided that one fulfills their obligations and avoids prohibited acts. Spending in the path of Jihad is superior to performing voluntary Hajj.
