Nail biting is not considered haram (forbidden) in Islam. However, it is discouraged as a bad habit with potential health risks.
According to Islamic teachings, nails are believed to hold the "dirt of sins," making it preferable to avoid biting them. While not forbidden, nail biting is considered makruh (disliked) due to its unappealing appearance and potential for introducing germs into the body.
Some resources suggest that nail biting could be harmful, potentially leading to leprosy or infections from germs trapped under the nails. However, it's important to note that these claims require further investigation and should not be taken as definitive medical advice.
It's crucial to understand that Islam encourages individuals to strive for self-improvement and avoid harmful habits. While nail biting isn't explicitly forbidden, the emphasis on personal hygiene and striving for positive behavior makes it a practice that Muslims are generally advised to avoid.
