First: It is permissible for you to perform Hajj on behalf of your dead relatives if you yourself have already performed Hajj. (Part No. 9; Page No. 32) Second: It is permissible for you to give Sadaqah (voluntary charity) on behalf of all your relatives together or on behalf of each one of them separately. Third: It is permissible for you to include your uncle and parents in your Waqf and this is considered an act of gratitude and kindness to them in case you have not started your endowment yet. However, if you have already started the Waqf, then you should not change it. In fact, it should remain as you have started it as long as it agrees with the sanctified Shari`ah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
