Prohibitions that are taken too lightly

Praise be to Allaah; we praise Him and seek His help and forgiveness. We seek refuge with Allaah from the evil of our own souls and from our evil deeds. Whomever Allaah guides will never be led astray, and whomever Allaah leaves astray, no-one will guide. I bear witness that there is no god worthy of worship but Allaah alone, with no partners or associates, and I bear witness that Muhammad, sallallaahu 'alayhi wa sallam, is His slave and Messenger.
