The Obligation of Performing Hajj Immediately when its Conditions are Fulfilled and not Delaying It:
The Messenger of Allaah (sallallaahu `alaihi wa sallam) said:
“He who intends to perform Hajj must do so immediately, for he may fall sick, lose his mount or be prevented by some other need.” And in another narration:
“Hasten to the Hajj for none of you knows what might come up before him.”
