All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
We ask Allah to grant you further success to do righteous deeds and increase your desire and keenness to do so. There is no doubt that the reward of Hajj is great and multiplied. The Prophet said: "Whoever performs Hajj and neither has sexual intercourse nor commits sins (during Hajj), he will return free of his sins as he was on the day his mother gave birth to him." [Saheeh (Authentic)] There are many proofs to indicate the virtues of Hajj.
The Hajj which is the greatest in reward is undoubtedly the obligatory Hajj. There is no doubt that the reward of the obligatory act of worship is greater than that of the voluntary act. In a Qudsi (sacred) Hadeeth, Allah, The Almighty, Says: "My servant draws not near to Me with an act better than what I have made obligatory on him. My servant continues to draw near to me by doing voluntary acts until I love him…." [Al-Bukhari]
This is clear evidence that the reward of the obligatory Hajj is greater than that of the voluntary one.
Allah knows best.
