I don't know the rituals of Hajj and I want to perform Hajj, so what should I do?

Whoever intends to perform Hajj must learn its description, or carry a booklet by one of the trusted scholars and act upon what is in it. Among the useful books are: "Al-Tahqiq wal-Idah" by Ibn Baz, and "Manasik al-Hajj wal-Umrah" by Ibn Uthaymeen. If something is unclear to him, he should ask the people of knowledge. He should also accompany a scholar or a student of knowledge to teach him the rituals, as Allah Almighty says: (So ask the people of the Reminder if you do not know) [An-Nahl/43].
