Hazrat Ibn Abbaas R.A. reports that Rasulullah Sal’am said: “whoever desires to perform Hajj, should hasten towards performing i.” (this Hadith encourages the performing of Hajj as soon as is possible after having made sincere intentions towards it, as was said by Rasulullah (Salallaho Alaihi Wassallam)).
In another Hadith it has been stated: “Hasten to perform your obligatory Hajj, for one knows not what shall happen (to prevent it).” (Targheeb)
In one Hadith it is stated: “Make haste to perform Hajj, because one knows not what lies ahead. Perchance illness may overtake you or some other necessity (may demand your attention). (kanz)
In one Hadith it is stated: “Hajj should be performed before nikaah.”
In a further Hadith it is also said: “Whoever has to perform Hajj should do so in haste, for a sickness may overtake him, or his means of conveyance may become unavailable, or some other necessity may prevent his departure.” (Kanz)
In one Hadith it is said: “Do hasten towards Hajj before some excuse prevents it.” (Kanz)
In view of these Ahaadith, the majority of Imams from among the Imams of Fiqh, are of the opinion that Hajj should be performed at the first opportunity after it becomes obligatory on a person. Should he delay, he is a sinner. Rasulullah Sal’am is reported to have said further: “Perform Hajj, it holds twenty times more reward than Jihaad.” (Kanz)
In one Hadith it is stated: “To perform Hajj is to make Jihaad and to perform Umrah is to make nafil.” (Kanz)
