Visit graves, keep sacrifical meat for as long as you wish , drink nabdih from any vessel but not intoxicant .

This hadith is about the Prophet Muhammad's changing of certain Islamic rulings. He used to forbid people from visiting graves, keeping sacrificial meat for more than three days and drinking Nabidh unless it was made in a water skin. However, he later changed these rulings and allowed people to visit graves, keep sacrificial meat for as long as they wish and drink Nabidh from any vessel but not intoxicants. This hadith teaches us that the Prophet Muhammad was open to change when necessary and that we should be too if it is beneficial for us or our society. It also teaches us that we should stay away from intoxicants as they are forbidden in Islam.
