Brief Explanation
Benefits: … In this hadith, the price of a dog has been declared as the food of the Age of Ignorance (Jahiliyyah). Since this is an act of Jahiliyyah and a filthy and unlawful business, therefore our Shari‘ah has termed it as the food of Jahiliyyah and declared it forbidden (haram).
