When a person dies his actions are terminated except for three: continuous charity (sadqah jariya), beneficial knowledge, and a righteous child who prays for him. Muslim
Benefits of Sadaqah in Islam
The benefits of these charitable actions are defined by many of the teachings of The Holy Prophet Muhammad PBUH. These actions are so rewarding that they will continue long after a person is gone as long as others continue to enjoy the benefits of the act.
You can also give sadaqah jariyah (ongoing charity) on behalf of your loved ones, and they will continue to receive the reward of the charity as long as others continue to benefit from it.
We at Minhaj Welfare Foundation have a number of different campaigns and humanitarian projects supporting the poor and deprived people across the world. Your support in form of Sadaqah will help us keep going on with welfare projects.
