(Fatwa: 656/ 88-Tatimmah/SN=5/1439)
You are the sole owner of your properties during your lifetime; no one has any share in it. However, if at the time of your death, your wife, daughters, brothers and sisters are alive then whatsoever remains after giving the wife and daughters it shall be divided among the brothers and sisters as per the rule of للذكر مثل حظ الأنثيين(male will get double of female’s share). However, if you keep something with you as per your need and distribute the remaining one during your lifetime as per the above mentioned details then too there is no harm. However, it should be noted that in case of distributing one’s property during lifetime the share of each heir should be given completely into his/her possession otherwise they shall not be considered owner; since what is given during lifetime it is not inheritance rather it is hibah which takes place only after the gifted person takes possession of it.
Allah knows Best!
