The Muslim's concern with knowing the rulings of acts of worship, particularly Hajj

Question:
May Allah reward you with good and do you well. Many of our Muslim brothers fall into errors like this. Shaykh Salih, one of them comes with the intention of performing Hajj, but he carries it out in a manner similar to this. Is there a general word for our Muslim brothers if they wish to come for Hajj or 'Umrah? May Allah reward you with good.

Answer:
It is obligatory for the Muslim in Hajj and other acts of worship not to enter into any act of worship until he knows its rulings and how to perform it. So he must read and ask how to perform Hajj? What are the rituals of Hajj? He should also be with a group that knows the acts of Hajj, walk with them, and do what they do.
This is the way to perform the rituals of Hajj as required. Either he reads, asks, and applies what he has learned, or he travels with people who are proficient in the acts of Hajj and does what they do. This is what is obligatory upon him. As for him being alone, not knowing, and mixing up the acts of Hajj or the acts of 'Umrah out of ignorance, this is not permissible and leads to defects and shortcomings, and perhaps to the invalidation of the act of worship for which he came. Yes.
