Described as a gem in Islam, intellect can lead all individual and social behaviours towards balance, appeal and godliness. Given the utmost importance of protecting intellect in this divine religion, everything from eating and drinking to reading, listening and entertainment is thus considered haram [ viz. remains prohibited] if it makes threats to the health of mind and soul. In general, narcotics and substance abuse in all forms can have crushing and all-encompassing effects, that is, inflict heavy blows on the (...) body, soul, mind, willpower and religion in a person and consequently destroy life in the family and society. The continuation of life as well as the stability and survival of this holy institution accordingly depends on many factors, including addiction tendency (AT) and sexual dysfunction (SD). It is also obvious that the balance and optimal use of sexual instinct on the accepted path of religion will be the key to the family health and strength. Altogether, the role of AT and SD on intention to divorce (ITD) in Indonesian Muslim couples ( n = 450) was investigated in 2022 in this study, wherein one partner had previously attended addiction treatment centres over the last 6 months. The study results ultimately demonstrated that AT could induce SD and consequently raise ITD among Muslim couples. Contribution: The study results confirmed the harmful impacts of AT on SD among Muslim couples, which could increase their ITD. In view of this, it was suggested to promote religious teachings in the family to benefit from their positive effects. (shrink)
