Ruling on donating some money to charity organizations during one's lifetime

Q: Being a social worker, and having worked in the countryside and in large towns, I decided to do the following:First, to grant a part of my inheritance as assets or cash after selling the assets to a local registered entity for taking care of the handicapped people, so that I will take part in fulfilling their mission towards the handicapped people. This gift is going to be registered in a contract or a legal deed.Second, to grant another part of this inheritance in cash to the Ministry of Social Affairs in Egypt to establish a training center in my father's village to provide services there. The priority of joining this center will be for our relatives and their children if they want to. (Part No. 16; Page No. 175) Third, to keep a part of this money to support me in my later days and illness.First question, is this permissible in Shari`ah (Islamic law), especially that I dispose of my money during my lifetime? I intend by these grants to make the maximum number of needy people benefit from them.Second question, as for the part I will keep for my later days, it is going to be inherited by my heirs when I die.Please advise, with many thanks.

A: It is permissible for you to grant a part of your wealth to a local entity for taking care of the handicapped people. It is also permissible to grant another part to the Ministry of Social Affairs to establish a training center in your village that provides training in useful topics, as both matters include a public benefit. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
