What the one who wants to do Hajj must do is learn how to do Hajj or at least take with him a small book in simple language by one of the trustworthy scholars who are known to follow the Sunnah, and act upon what is written in it.
Useful books of this nature include:
1. Al-Tahqeeq waâl-Eedaah li Katheer min Masaaâil al-Hajj waâl-Umrah waâl-Ziyaarah by Shaykh Ibn Baaz (may Allah have mercy on him) available in English under the title Verifying and Explaining Many Matters of Hajj, âUmrah and Ziyarah, published by Darussalam;
2. Manaasik al-Hajj waâl-âUmrah by Shaykh Ibn âUthaymeen (may Allah have mercy on him).
If there is anything he does not understand, he should ask the scholars. He should keep company with one of the scholars or seekers of knowledge so that he can teach him the rituals one by one.
So he should ask about groups that are keen to have one of the daaâiyahs or seekers of knowledge with them, and go out with that group.
Shaykh Ibn âUthaymeen was asked a similar question and he replied:
My answer to this is that Allah answered it when He, may He be exalted, said (interpretation of the meaning): âSo ask of those who know the Scripture, if you know notâ al-Nahl 16:43. What the one who wants to do an act of worship but does not know how must do is to ask people of knowledge about it so that he may worship Allah on the basis of knowledge, because one of the conditions of worship is sincerity towards Allah, may He be glorified and exalted, and following the Messenger of Allah (blessings and peace of Allah be upon him), and it is not possible to follow him except by learning what the Prophet (blessings and peace of Allah be upon him) did of acts of worship in both word and deed. Hence I say to this questioner: if you want to do Hajj but you do not know its rulings and rituals, then you have to ask people who have knowledge of that. I urge the one who wants to do Hajj to accompany one of those who have knowledge, such as seekers of knowledge who are known for their knowledge of the rulings that have to do with Hajj, so that he can follow what they tell him to do.
