I was watching some videos from Anti-Shia, where they start saying that Shia believe that the 12 Imams are equal to Allah (Swt) because some Shia say’s (Ya Ali) or (Labaika Ya Hussein) when they are making Dua for help or forgiveness. Is this true? Or are they liars?
Thank you for your question. This is an unfortunate misconception. There is nobody or nothing that is equal to God. He possesses every beautiful Attribute and cannot be fathomed by the intellect or described by words. The Shia believe this and so if they ask for help from the Imams (as) it is in the same way that the sons of Ya'qub asked Ya'qub (as) to seek forgiveness for them after they realized their mistake in dealing with Prophet Yusuf (as) (see Qur'an, 12:97) where Allah quotes the sons as saying to their father:
"O our father, ask for us forgiveness of our sins...".
Hence asking for the intercession of those who are closer to God is a Qur'anic concept as well as an intellectual one. But the ultimate forgiver and provider is Allah.
May you always be successful
