In as much I dnt want to offend the sensibilities of my muslim brothers, I would want them equally to satisfy my curiosity. I have asked this same questions severally and I haven't got the right answer to it. So I wouldn't mind if some matured muslim brothers can help me out.
I have observed that whenever the yoruba muslims are preaching(waasi), they always use this Ilorin-Yoruba dialect, irrespective of the speaker, whether ijebu, ilesha, ondo, just name it. Though the Ilorin-yoruba dialect is always sweet to hear, but at the same time, I want to know why they dnt use any other language or dialect to preach.

I hope they wouldn't ban this oooo
