Can sihr run in a family or be inherited?

Practitioners report seeing the same problems recurring across a family: several siblings with delayed marriages, repeated business failures across generations, or a pattern of marital breakdown appearing in each generation.

The explanation offered is that sihr directed at a household or a parent may continue to affect descendants.

Be extremely careful with this idea. It has done a great deal of harm. It leads families to believe they are cursed, to view their own difficulties as inescapable, and in many cases to accuse relatives, in-laws or neighbours of having caused it. Marriages and extended families have been destroyed on nothing more than a suspicion of this kind.

Families also share genetics, culture, financial position, expectations and learned patterns of behaviour. These explain recurring difficulties across generations far more reliably than anything else.

No one is cursed by lineage in Islam. Nobody carries another person's burden, and your circumstances are not sealed by what happened to your grandparents.
