Changing one's name

Q: My name is Asad. At times I feel depressed of my wrong and think that I am actually an "Asad of my nafs or an "Asad of sin." However, I want to be an Asad of Allah Ta'ala. Please advise if it would be appropriate to change my name to 'Asadullah.'

Bequests

Q: My father passed away recently. We are 7 siblings and 1 half sibling from my dad's previous marriage. My dad had bequeathed verbally that his car should be sold and the money should be used in building a musjid. My dad also bequeathed verbally that he has 50000 rands aside for his two daughters marriages and this money should be split between the two. My dad had income coming in from a rental property as well. And finally he has a paid house that my brother contributed to it. How is all this distributed? Can the verbal bequeath be accepted? Do gifts / bequeaths have to be only from his 1/3 of the total property? Is gifts and bequeaths separate? Do we have to first to subtract all the funeral expenses,debts fidya then distribute? I understand this should be done from the 1/3. Is this correct? How is the rental property going to be distributed?
