It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) forbade three things: visiting graveyards, eating the meat of sacrifice after three days, and drinking nabidh (fermented drink) in dubba, naqir, hantam, and muzaffat vessels. Then, after some time had passed, he said: I had previously forbidden you from three things, but now my opinion about them has become clear. I had forbidden you from visiting graveyards, but now my opinion is that it softens the heart, brings tears to the eyes, and reminds one of the Hereafter, so visit the graveyards, but do not indulge in idle talk. Similarly, I had forbidden you from eating the meat of sacrifice after three days, but now my opinion is that people give this meat as gifts to their guests and keep it stored for those who are absent, so you may keep it for as long as you wish. Also, I had forbidden you from drinking nabidh in those vessels, but now you may drink from whichever vessel you wish, but do not drink anything intoxicating. Now, whoever wishes, let him seal the mouth of his waterskin against anything sinful.
