Purpose – This study aims to provide insights on the influence of Muslim consumers’ knowledge on products subjected to contemporary fatwa ruling and their subsequent cognitive and behavioural responses. Design/methodology/approach – MANOVA and MANCOVA were used to examine the influence of religious orientation on young Malaysian Muslims’ product knowledge, and the extent of religious orientation and gender on Muslim consumers’ attitude and behaviour towards three contemporary fatwa rulings of products. Findings – Respondents’ religious orientation differentiates their knowledge on fatwa prohibition ruling of selected brand and behaviours. Consumers’ religious orientation and gender explain consumers’ behavioural responses to variables of the Theory of Planned Behaviour for three behaviours. Evidence suggests that ruling types affects (conditional and unconditional) consumers’ responses. Research limitations/implications – Greater insights are provided on Muslims’ motivation to search information of controversial products, and their subsequent perception and behavioural reactions to controversial products. Findings are limited to the Malaysian Muslim consumers. Practical implications – The fact that contemporary fatwa reached young Muslim generations indicates that managers have to be wary of fatwa to predict Muslim consumers’ marketplace behaviours. Social implications – A significant number of young Malaysian Muslims are keeping abreast with contemporary fatwa. This suggests that they received an early and substantial exposure to Islamic way of life through their socialisation. Originality/value – This study offer insights into the understandings of the young Muslim generation regarding contemporary fatwa on products, and revealed significant findings in relation to consumer product knowledge and religious influences on consumer behaviour.
