It is narrated from Hazrat Abu Sa'id Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: I had forbidden you from going to the graveyards, but now you may go, for there is a lesson in them. And I had forbidden you from drinking nabidh, but now you may drink it; however, I do not permit any intoxicating drink. And I had forbidden you from keeping the meat of sacrificial animals (for more than three days), but now you may eat it.
