<b>Guidance from the Hadiths:</b><br> 1) The Islamic Shariah is perfect in all aspects, even in the fine details concerning the etiquette of eating and drinking.<br> 2) The forbiddance to blow into the vessel, lest harmful things come out. So, this instruction is aimed at protecting health and warding off harms. Is there a legislation more sublime than Islam?!
