The Muslim should hasten to fulfil the duty of Hajj when he is able to do it, because he does not know what will happen to him if he delays it. Allaah says (interpretation of the meaning):
And Hajj (pilgrimage to Makkah) to the House (Kabah) is a duty that mankind owes to Allaah, those who can afford the expenses (for one's conveyance, provision and residence)
[Aal Imraan 3:97]
And it was narrated that the Prophet (peace and blessings of Allaah be upon him) said: Hasten to do Hajj - meaning the obligatory Hajj - for none of you knows what will happen to him. Narrated by Imam Ahmad (may Allaah have mercy on him), 1/314; classed as hasan by al-Albaani in Irwa' al-Ghaleel, 990.
And Allaah is the Source of strength.
