It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that once, while she was combing her hair, she was suddenly startled by the call of the Messenger of Allah (peace and blessings be upon him) from the pulpit; he (peace and blessings be upon him) was saying: "O people! While I am at the Pond, you will be brought before me group after group, then some of you will turn away this way and that. I will say: What is the matter with them? Come to me! Then a caller will call out and say: They changed (the religion) after you. So I will say: Away with them, away with them!"
