What should a wife do if her husband is addicted to drugs, fears Allah, she has three children with him, and she fears his condition might worsen or he might commit suicide if she leaves him?

The sister should be advised to stand by her husband during his repentance from drug addiction, and to seek help from specialized medical centers for addiction treatment. She should also remind him to fear Allah and remember death, encourage him to abandon his current state, and give him hope for recovery.
