Sayyiduna Sahl bin Sa'd al-Ansari (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "By the One in whose Hand is my soul, you will surely follow those before you exactly alike."
Ahmad recorded it, and al-Tabarani recorded something similar, adding these words: "So much so that if they entered a lizard's hole, you would follow them. The people said: O Messenger of Allah! (Are those before us) the Jews and the Christians? The Prophet (peace and blessings be upon him) said: Who else but the Jews and the Christians?" Ahmad's chain contains Ibn Lahi'ah, in whom there is weakness; al-Tabarani's chain contains Yahya bin Uthman, who narrated it from Abu Hazim, and I do not know him; the rest of the narrators of both are thiqat (trustworthy).
