What is the share of the three brothers from the inheritance of their deceased brother who left behind a wife and three daughters? And is it Islamically permissible for the deceased to sell half of what he owns to his wife as a gift without monetary compensation?

Full brothers do not have a predetermined share of their brother's inheritance. Rather, they inherit what remains after the wife's share (one-eighth) and the daughters' share (two-thirds), dividing it equally among themselves.

The matter of inheritances is serious and complex, and a mere fatwa is insufficient. Instead, it must be referred to the Sharia courts for investigation, due to the possible existence of other heirs, wills, debts, or rights of which the heirs may be unaware, and which take precedence over their claim.
