Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Hudhaifah (may Allah be pleased with him) that he said: The Dajjal will not emerge until his disappearance becomes no less beloved to a believer than his emergence, and his emergence will not harm a believer more than the pebble he picks up from the ground, and the knowledge (about the Dajjal) among the believers, whether near or far, will be equal.
