In Islam, it is recommended to address one's husband with affection and respect. The most common and appropriate term used to address one's husband is "husband" or "زَوْج" (zawj) in Arabic. This term reflects the marital relationship and acknowledges the role of the husband as a spouse.
Using a husband's own name without any title (e.g., just calling him by his first name) is generally not considered disrespectful or prohibited in Islam, but it may vary depending on cultural norms and personal preferences within different Muslim communities. It's essential to consider the cultural context and individual preferences of the couple when addressing each other.
However, using a respectful and affectionate term like "husband" or "zawj" is encouraged as it fosters a loving and caring atmosphere within the marriage. Islam emphasizes the importance of maintaining a healthy and respectful relationship between spouses, and using appropriate terms of endearment can contribute to that. As with any aspect of Islamic practices, sincerity, love, and respect are the key factors that should guide how a couple addresses each other.
