(As Sunanul Kubra: 11866, Musannaf Ibn Abi Shaybah: 36564)
Through the piety of a person, Allah rectifies his children, his grandchildren, the people living in his home as well as the people living in the neighbouring homes. They all remain under the protection of Allah, as long as this person remains among them.
And Allah Ta’ala Knows best.
