The Jahiliyyah practice that was gradually phased out is alcoholism. Jahiliyyah refers to the pre-Islamic era in Arabia, characterized by ignorance and unbelief in God. Alcohol consumption was widespread during that time, and it was considered a normal social activity. However, after the revelation of Islam, the consumption of alcohol was gradually phased out and eventually prohibited altogether. Muslims believe that alcohol consumption has harmful effects on individuals and society, leading to addiction, health problems, and social issues such as violence and family problems. Therefore, Muslims are forbidden from consuming or dealing with alcohol in any way.
