OSMAN SIDEK and ENON MANSOR is a husband and wife writing team. They met in university and married after graduation. Soon after, they both began working as trainers in marriage preparation courses conducted by the Muslim Converts’ Association Singapore (MCAS), the Islamic Religious Council Singapore (MUIS) and Singapore’s then Ministry of Community Development, Youth and Sports (MCYS). In 1998, they co-wrote Tranquil Hearts – A Guide to Marriage, which was co-published by MCAS and MUIS and is still being used as the textbook for the marriage preparation programme in MCAS. In 2011, they collaborated with an Islamic scholar and a social worker to design and conduct Suara Kekasih, a programme of sexual enrichment workshops for married couples in Malay. In August 2021 they conducted an online seminar entitled “Sex, Soul and Islam” organised by the Islamic Institute for Development and Research, UK [IIDR].
