How is the estate of a man who left behind two full sisters and a wife to be distributed, and what is the ruling concerning the chalet he wrote over to his wife during his death sickness?

What a husband writes to his wife during his lifetime may be a gift or a will. What the husband gifted during his death illness is not enforceable and is returned to the estate. It is necessary to refer to the Sharia judge to determine the status of the chalet (whether it was a will or a gift) and whether it was done while the husband was healthy or ill. If the heirs are a wife and two sisters, the wife receives one-quarter due to the absence of a direct descendant, and the two full sisters receive two-thirds, with the remainder being returned to them. The estate is divided into eight shares: two shares for the wife, and three shares for each sister, as a prescribed share and by return. It is advisable to consult the Sharia courts for the division of inheritances.
