The sheikh whose video with a cat that went viral during Ramadan is an Algerian Imām and his name is Sheikh Walid Mehsas. He is still very much alive.
The Sheikh that passed away is Sheikh AbdulLāh Kāmil, until his death he resided in the United States of America. The Sheikh in the second frame cladded in a white jalābiyah, on a white cap, and full of a smile (RahimahuLlāh).
Sheikh Kāmil is a blind Qāri, an Egypt National with a sonorous voice that usually wow everyone that listens to him.
He reportedly passed away in New Jersey. He did not come for solāt in the Masjid where he usually prays. When he was checked upon, they found out that he had died.
Yes! They look alike but they are two different persons.
May Allāh have mercy on his soul and grant him the highest rank in Jannah.
Aameen
