“I once asked abu ‘Abd Allah (a.s.), about the case of my girl who was pregnant and I made a vow and commitment for Allah, most Majestic, most Glorious, that if she gives birth to a boy, I will help him to perform al-Hajj or I will perform al-Hajj on his behalf. He (the Imam) said, ‘A man made a vow and commitment for Allah, most Majestic, most Glorious, about his son that if he matures he will perform al-Hajj for him or help him to perform al-Hajj. The father died and the boy became mature thereafter and came to the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, who commanded him to perform al-Hajj by means of what his father has left behind.’”
