The Prophet (ﷺ) said, "The Hour will not be established till my followers copy the deeds of the previous nations and follow them very closely, span by span, and cubit by cubit (i.e., inch by inch)." It was said, "O Allah's Messenger (ﷺ)! Do you mean by those (nations) the Persians and the Byzantines?" The Prophet said, "Who can it be other than they?"
Sahih al-Bukhari Book 96, Hadith 49
← Previous Hadith `Umar bin Al-Khattab asked (the people) about the Imlas of a woman, i.e., a woman who has an abortion because of having been beaten on her `Abdomen, saying, "Who among you has heard anything about it from the Prophet?" I said, "I did.'' He said, "What is that?" I said, "I heard the Prophet saying, "Its Diya (blood money) is either a male or a female slave.' " `Umar said, "Do not leave till you present witness in support of your statement." So I went out, and found Muhammad bin Maslama. I brought him, and he bore witness with me that he had heard the Prophet (ﷺ) saying, "Its Diya (blood money) is either a male slave or a female slave."

Sahih al-Bukhari Book 96, Hadith 48 Next Hadith → The Prophet (ﷺ) 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 a mastigure, you would follow them." We said, "O Allah's Messenger (ﷺ)! (Do you mean) the Jews and the Christians?" He said, "Whom else?"
