A man wants to cut off the water and electricity supply of his ex-wife.

Answer

Cutting off her water and electricity supply will be of the worst kind of zulm. Rasulullah (Sallallahu alayhi wasallam) said:

"Whoever gives someone water to drink in a place where water is available plentiful, his reward is like emancipating a Muslim slave. And, if he gives someone water to drink where water is not freely available, then it is as if he has brought to life a dead Muslim."

It is absolutely intolerable and unacceptable that a man threatens his children‟s mother with deprivation of water. All his ibaadat, if he has any, will go to waste. This will be zulm of the worst kind. A prostitute was forgiven and granted Jannat for having given a dog some water to drink. But here a man threatens to deprive the mother of his children from water. Indeed he is a stonehearted, cruel brute.
