The physical features of Hazrat Mahdi (as)
In addition to Hazrat Mahdi’s (as) good manners and intellectual struggle, our Prophet (saas) has also described his physical characteristics in great detail. The Prophet’s (saas) descriptions of Hazrat Mahdi (as) are so detailed and explicit that people seeing Hazrat Mahdi (as) when he appears will immediately recognize him.
It is revealed in one verse that the People of the Book will recognize our Prophet (saas) “as they recognize their own sons:”
Those We have given the Book recognize it as they recognize their own sons. Yet a group of them knowingly conceal the truth. (Surat al-Baqara, 146)
This verse is also a figurative reference to the recognition of Hazrat Mahdi (as). When Hazrat Mahdi (as) appears, people will recognize him in the light of our Prophet’s (saas) descriptions, as they recognize their own sons. Despite this, however, some people will still pretend not to recognize this blessed individual, and will deny him.
