We are told in the hadith that Hazrat Mahdi (as) will have “a beautiful face and beautiful hair.”In addition, we are told that Hazrat Mahdi (as), described above as having “a wide face”and in other hadiths as having “a broad forehead,”will also have a largish head, like the holy head of the Prophet Muhammad (saas).
Al-Qirmani al-Dimashqi (1019), a famous Sunni scholar, writes in his Akhbar al-Duwal:
“… He [Hazrat Mahdi (as)] WILL BE OF MEDIUM HEIGHT WITH A BEAUTIFUL FACE AND HAIR...” (Al-Qirmani al-Dimashqi, Akhbar al-Duwal, p. 117 - printed in 1382 AH)
Abd al-Malik al-'Isami (1111) is a well-known historian residing in Mecca. In his four-volume work of history known as Simt al-Nujum al'awali he says: "... He [Hazrat Mahdi (as)] IS A TEMPERATE YOUNG MAN WITH A BEAUTIFUL FACE AND HAIR, A FINE NOSE AND BROAD FACE."(Abd al-Malik al-Shafi'i al-Makki al-'Isami, Simt al-Nujum al'awali, Vol 4, p. 138; Abdullah Turan, Hz. Mehdi Aleyhisselam [Hazrat Mahdi (as)], Al-i Taha Press, p. 157)
