Assalamu alaykum,
A good orator, says some good things, however, he is not a Muslim scholar, nor is he someone who understands the solutions to the problems Muslim faces.
As practising Muslims, we believe the ultimate solution to our problems start from our ownselves, by bettering ourselves through returning to Islam.
Mehdia Hassan is pro-Iran and all that entails. Similarly Asghar Bukhari, a shiite, has his own agendas.
May Allah unite and guide us all upon the truth and help us with attaining the best in this life and the akhirah. amin
