بسم الله الرحمن الرحيم
(Fatwa: 1009/739/L=1431)
If the two elder sons took the two shops of their father in their care with the permission of all their brothers and sisters whether the permission was given in explicit words or implicitly, then all the heirs shall be eligible to get shares in the two shops and the property bought with the income earned through it and shall have share in all the property left by their father.
Allah knows Best!
