Is there a difference between al-Ittihadiyyah and tawhid?

Question:
I ask Allah to do you good. Your Eminence, father, the questioner asks: Is there a difference between al-Ittihadiyyah and tawhid?

Answer:
Tawhid (the oneness of Allah) is what the messengers came with, and it is the truth. It is worshipping Allah alone, having no partner with Him, singling Him out in His lordship, His divinity, and His names and attributes. This is the truth, this is tawhid. As for al-wahdah (unity), its meaning is that there is no Creator and no created being; the entire universe is the Lord in their view, and He is Allah. Glory be to Allah. Yes.
