What is the ruling on exhuming and relocating a Muslim grave, and when is it permitted?

Summary

Exhuming and relocating the grave of a Muslim is originally forbidden. It is allowed only for reasons recognised by Islamic law, such as burial in a non-Muslim cemetery, the body not being washed or given tayammum, not facing the qiblat, or being shrouded in unlawful cloth. Other reasons include land to be developed for public benefit such as a road, land at risk of erosion or flooding, a woman who died six months pregnant with a foetus believed to be alive, and other excuses permitted by syarak. Applications for relocation must be submitted to the Selangor Islamic Religious Department, which investigates them.
