In the Words of His Holiness Mirza Ghulam Ahmad, The Promised Messiah and Mahdi (as)

A few days ago I was meditating whether a certain hadith:

[The Signs will appear after two centuries]

means that the Promised Messiah would appear towards the end of the thirteenth century of the Hijrah and whether this humble one is included within the meaning of that hadith. Then my attention was, in a vision, directed to the value of the letters of the name set out below as indicating that the Messiah would appear at the close of the thirteenth century. and this had been determined in advance by divine decree. The name is:

The value of the letters comprised in this name is exactly 1300. In this village of Qadian there is no one else named Ghulam Ahmad. Indeed, it has been conveyed to me that there is no one else in the whole world who bears the name Ghulam Ahmad Qadiani. It has been the way of Allah with me that He, hallowed be His name, conveys some mysteries to me which are comprised in the value of the alphabet.

In Arabic, every letter is assigned a numerical value. Adding the numerical values of the Arabic letters in the name

[Ghulam Ahmad Qadiani] is calculated to be 1300 [1,000 + 30 + 1 + 40 + 1 + 8 + 40 + 4 + 100 + 1 + 4 + 10 + 1 + 50 + 10 = 1,300].
