Truth has come

Imam ‘Ali (PBUH) has said:

When Mohammad (PBUH&HP) was born, all idols which were inside Ka'bah fell on their faces and once the night descended upon the land, a heavenly voice was heard from the sky:

Truth has come and the falsehood has perished, surely falsehood has been bound to perish.

The world became bright on that night and all beings happy and praised the one and only Allah. Eblis (Satan), while running away, confessed that Mohammad was the most superior creation ... .

(Montahel-Aamaal, ...)

The heavenly statement which was heard from the sky on the night the Prophet Mohammad (PBUH&HP) was born - Truth has come and the falsehood has perished, surely falsehood has been bound to perish - is truly a celestial statement, it is a meaningful Promise which the Prophet Mohammad later revealed it, by God's command, to the people as a verse of Glorious Qur'an.

(Qur'an, Surah Esra, verse 81)

In Continuation and fulfillment of this heavenly Promise, when Hadrat Mahdy (PBUH) -the last Infallible Successor of the Prophet- was born, this same Qur'anic verse was written on his arm with letters which were from light. (Sunni Documents, Yanaabi-Ol-Mawaddah, ...).

Yes, the Promise of abolishment of all that is vain was given by every single Divine Prophet and it became manifest by Mohammad's and his last Successor’s births and the fulfillment of it, shall be at the light-full hand of Mahdy (PBUH). May Allah hasten the Appearance of the Everlasting Truth ... .
