Since, we don’t know him we would not be able to answer about him. The reference you gave about kissing the hands of abu bakar is also not clear from our point of view. Sometimes, some people attribute that kissing of one’s thumbs and applying them to their eyes when the name of the prophet peace be upon him is mentioned in the adhan. If you are referring to this incident, then according to one scholar, this is a fabricated story. There is no authenticity to this. We don’t have all the information or more details about shah ataullah bukhari r.a. But briefly, we can say that he was a great scholar and orator. He also has served his religion very well, he always supported the truth, he also sacrificed a lot during his time, and suffered many difficulties.
We cannot give our opinion about the contemporary scholars.
However, we can give an opinion about them based on their school of thought. So you have to tell us what school of thought, this personality belongs to.
