I have also been told that any clothes a newborn baby wears in the first 40 days are not allowed to be worn after this period of time. To me this would imply that a newborn baby would be impure? Is a baby born pure or not? I would like to know whether this is a cultural thing or islamic. 3. I would also like to know the meaning of the name 'Yusuf'. I have gathered that this name was a prophets name, but i am struggling to find a real meaning for it. Thank you.
