Hadith: The Hour will not be established until you fight the Turks, who have small eyes, red faces, and flat noses. Their faces look like hammered shields. Again, the Hour will not be established until you fight people wearing shoes made of hair

عن أبي هريرة رضي الله عنه عن رسول الله صلى الله عليه وسلم قال: «لا تقومُ الساعةُ حتى تُقاتلوا التُّرْكَ: صِغارَ الأَعين، حُمْرَ الوجوه، ذُلْفَ الأنوف، كأنَّ وجوهَهم المِجانُّ المُطْرَقة، ولا تقومُ الساعةُ حتى تقاتلوا قومًا نِعالُهم الشَّعر».
[صحيح] - [متفق عليه]

Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "The Hour will not be established until you fight the Turks, who have small eyes, red faces, and flat noses. Their faces look like hammered shields. Again, the Hour will not be established until you fight people wearing shoes made of hair."
Sahih/Authentic. - [Al-Bukhari and Muslim]

Explanation

Before the advent of the Hour, the Muslims will fight the Turks, who are distinguished by their small eyes; white reddish faces, because of the cold weather; and short, flat noses. Their faces resemble a shield for being broad and round and seem hammered for being plump and fleshy. And before the advent of the Hour, the Muslims will fight people who wear shoes made of hair. They are the same Turks who were previously mentioned, but they are mentioned with a different description here.
