Is Sathya Sai Baba the Dajjal (Antichrist), or the lesser Dajjal who paves the way for the greater Dajjal, especially given the "miracles" attributed to him and what has been said about scholars warning against him, and some being influenced by him?

We have no knowledge of the true nature of the man mentioned, who is said to be the Minor Dajjal. However, the Major Dajjal is alive and imprisoned on one of the islands. He will emerge in anger when the Muslims conquer Constantinople, claiming faith, then prophethood, then divinity.

As for the man mentioned, he is not the Major Dajjal, and there is no evidence for what is called the "Minor Dajjal." If the man claims to possess miraculous abilities, then he is one of the lying dajjal-like figures. It is not permissible to follow someone who flies in the air or walks on water unless it conforms to the Qur'an and Sunnah, for the Dajjal himself possesses supernatural feats, yet he is a cursed disbeliever.

The Prophet, peace and blessings be upon him, warned against the Major Dajjal and described him, and commanded seeking refuge from his trial. He also informed that there will be thirty lying dajjal-like figures before the Hour, and upon these, the devils descend and inspire them. The allies of Allah are the believing, pious ones, and the dajjal-like figures cannot be among them.
