Question: What is Hajj linguistically and what is it technically?
Answer: “All praise is to due to Allah Lord of the worlds and may peace and blessings be upon our master Muhammad, upon his followers, and Companions altogether. I bear witness that there is no God worthy of worship except Allah without a partner and I bear witness that Muhammad is His servant and Messenger
As for what follows: Hajj linguistically is intent. Technically it is to intent [to go] to the Sacred House to perform the well-known rites”
