Only that which poses as a barrier to water reaching all parts of the mouth is what renders Ghusl incomplete. Furthermore those stains are usually permeable anyway, so water will normally reach the teach. Where there is extreme hardship then the ruling is softened anyhow. Allahu Alam
Smoke stains do not stop water reaching teeth, hence ghusl will be valid. However, smoking is a really bad habit, dangerous for health, the smell (or stench, i would say) near somkers off puts many, and chain smoking also effect personal appearance, such as dirty stains on teeth. But it does not have any effect on ghusl validity. Allah knows best.
For a smoker before he does ghusl will he have to remove the marks on his teeth and if he cant remove these marks will his ghusl be valid Does anyone have any information about this and in genral rulings of ghusl in english Jazak allah
