Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said, "Those people who leave a gathering in which they have not remembered Allah, will conclude it as if it has foul odour similar to that of a rotten carcass of a donkey. And it will be a cause of grief to them."[Abu Dawud].
