Is it permissible for a husband to masturbate with his hand if he suffers from premature ejaculation, in order to fulfill his wife's needs and satisfy his own, given that his wife refuses to engage in marital relations daily or twice in a row?

Masturbation by hand is forbidden and is not permissible due to premature ejaculation. Treatment for this should be sought through lawful means. Masturbation by the wife's hand is permissible. The wife must respond to her husband's call for intercourse unless there is a valid excuse such as illness, menstruation, an obligatory fast, or harm. If they dispute over the number of times of intercourse, the judge's discretion should be resorted to. Both spouses must treat each other with kindness and each must fulfill the other's rights without delay or showing aversion.
