My son who works in Saudi Arabia offered to cover my hajj expenses. Is it permissible for me to use this money to make hajj on behalf of my mother?
 

 

It is permissible to make hajj from the money of:
- The pilgrim himself;
- the person on whose behalf the hajj will be performed;
- the money of another.
God’s reward to the person making hajj on behalf of another is proportionate to the hardships he encounters and the money he spends. Muslim and Bukhari related that the Prophet (peace and blessings be upon him) told 'A`isha that she will receive a reward for her 'umrah in proportion to her hardship or the money she spends.

The ruling
There is no objection to making hajj on behalf of your mother from the money gifted by your son for your own hajj, provided that you have previously performed your own hajj. God will reward you, your mother and your son because His bounty has no limits.
And God Almighty knows best.
