I went to SMO bookstore last night. My husband bought a book. A thick book. The title is "Muhammad : Riwayat hidup berdasarkan sumber terawal" by Martin Lings. It's a translation from the book "Muhammad : His life based on the earliest sources ". The price is RM76.00 but because of the 10% discount, it's RM68.40. 

I thought of buying a book but after my husband bought the biography book, I changed my mind. I think I want to read that book first. It's a must read book.
