Al-Bukhari recorded that Abu Hurayrah said that the Messenger of Allah said,

«كَيْفَ بِكُمْ إِذَا نَزَلَ فِيكُمُ الْمَسِيحُ ابْنُ مَرْيَمَ وَإِمَامُكُمْ مِنْكُم»

(How will you be when Al-Masih, son of Maryam (`Isa) descends among you while your Imam is from among yourselves) Imam Ahmad and Muslim also recorded this Hadith.
