His Excellence, the respectable Shaykh 'Abdul­'Aziz ibn Baz As­salamu 'alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you!) I will explain my problem to Your Eminence and I ask Allah to help you find a solution for it. We are three sisters and two brothers born to different mothers. Two of my sisters are full sisters but I have another mother. Our father, may Allah reward him well, wished to give each of us a piece of land in his lifetime. I am the elder of my sisters and brothers so my father came to me at first and told me that he had a piece of land in Al­'Umrah district and that he will give me half of it and build a Masjid (mosque) on the remaining part. I accepted his gift, thanked him and supplicated Allah for him. Afterwards, he told me that the concerned bodies of the government did not admit the division of the land and therefore he would give this land to my two sisters who may agree to sell or build over the entire lot, or one of them may assign her share to the other in return for a sum of money she gives to her sister. It is worth mentioning that both my sisters are employed and are able to pay the money even in installments. My father has another piece of land in Al­Riyadh which he gave to my brothers and another one which he gave to their mother who is not his wife anymore. He asked me to choose between two pieces of land in Al­Khubr and three in Al­Khafjy or two pieces in Al­Ta'if one of them in Al­Huda district and the other one lies in Buhrah; he gave me time to think about which one I would choose. I later chose the one in Buhrah district even though I had not seen it yet. He, on his part, gave me its title deed. Now, I find that I have been wronged; so is it permissible for me to ask him to replace this piece of land with another? Please, put your Fatwa at the bottom of my question. May Allah reward you best!
