Al-Lu'lu Wal-Marjan 1708 — The Book of Knowledge

Abu Sa'id al-Khudri Narrated from:

The Prophet صلى الله عليه وسلم said, “You will follow the ways of those nations who were before you, span by span and cubit by cubit (i.e., inch by inch) so much so that even if they entered a hole of mastigure, you would follow them.” We said, “O Allâh’s Messenger! (Do you mean) the Jews and the Christians?” He said, “Whom else?” ( Sahîh Al-Bukhârî, Hadîth No. 422, Vol. 9 )
