In the ocean of merits of Imam Mahdi (a.t.f.s.), one virtue and excellence which is very evident; is his similarity to the Holy Prophet (s.a.w.a.) to such an extent that even his name and agnomen is exactly the same as that of the Holy Prophet (peace be upon him and his holy progeny).
If the Holy Prophet (peace be upon him and his holy progeny) is the Master of Shariah, then Imam Mahdi (a.t.f.s.) is the one who will implement that Shariah in the entire world. One of these interesting merits is mentioned by the Ahle Tasanun scholar Hafiz Sulaiman Qunduzi in his book Yanaabee’ al-Mawaddah, chapter 94, p. 551 that Imam Jafar Sadiq (peace be upon him) said,
“The righteous successor is from my progeny and he is Mahdi (a.t.f.s.). His name is the same as that of the Messenger of Allah (peace be upon him and his holy progeny) and his agnomen is Abul Qasim, he will reappear in the last era and his mother is Narjis (peace be upon her). There will be a cloud cover over him which will shade him from the rays of the sun, follow him wherever he goes, and will call out in an eloquent tone,
هٰذَا الْمَھْدِيُّ فَاتَّبِعُوْهُ
‘This is Mahdi, obey him’.”
To summarise, just as clouds used to cover the Holy Prophet (peace be upon him and his holy progeny), similarly, a cloud will shade Imam Mahdi (a.t.f.s.), travel with him, and command the people to obey him.
We pray to Allah through the medium of the Holy Prophet (peace be upon him and his holy progeny) that He hastens the reappearance of Imam Mahdi (a.t.f.s.), keeps us in his protection, and includes us among his friends and helpers.
Aameen, O Lord of the worlds!
