Dear Sir, One small correction Mohammad Ali Jinnah did not converted himself to islam, It was his father His father was a Gujarati from Lohana community His father's full name was Zinabhai Poonjabhai Thakkar ( it can be spelled as Jhinabhai also) He himself was converted to muslim, and he named his son as Mohammad Ali Now, when Mohmmad Ali grew up with his own identity, he was ashamed of his father's hindu name. And under normal circumstances, his traditional full name would be Mohammad Ali Zinabhai Thakkar So, he changed, rather shortened his name, dropped surname Thakkar and respelled father's name from Zinabhai or Jhinabhai to Jinnah and created it as surname for his muslim identity. Thus he became Mohammad Ali Jinnah
