Cocolatti:
Please my question is to Yoruba Muslims . What is the difference between Asiwaju Musulmi & Baba Adinni. The late Alhaji Arisekola Alao was the Baba Adinni, now which one be Asiwaju Musulmi again?

Well, to start with, these are Titles peculiar to the Yorubas. All what you noted are just FEEL GOOD TITLES. Aare (Genaralsimo/President), Asiwaju( Leader) Baba Adinni (Adinni from the Arabic Word Deen meaning Way, Religion, Judgement) So, no matter the context how can anyone be the "Father of Religion/Way/Judgement)?

So, don't stress yourself, they are just FEEL GOOD TITLES.
