Mukhtasar Bukhari

Narrated by Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) from the Noble Prophet (peace and blessings of Allah be upon him) that he (peace be upon him) said: "You (Muslims) will surely follow the ways of those before you, span by span and cubit by cubit, so much so that if they entered the hole of a lizard (which is extremely narrow), you would also enter it." We asked, "O Messenger of Allah! Are the previous people meant the Jews and Christians?" He (peace be upon him) replied, "Who else?"
