God Almighty demonstrated many heavenly signs in support of the Promised Messiah(as). One of the signs He manifested in support of the Promised Messiah(as) was the sudden appearance of plague in the province of Punjab. On February 6th, 1898 Hazrat Ahmad(as) saw in a vision:
“Angels of God are planting black trees in different places of Punjab. These plants are very ugly, black, frightening and stunted. I asked the person planting these trees, what kind of trees are these? He replied that these were plague trees, which would spread in the country very shortly.” (Ayyam al-Sulh, page 121)
It is noteworthy that this virulent disease was unheard of in the history of Punjab. His opponents ridiculed him. Next winter, in fulfillment of this revelation, bubonic plague broke out in various cities of Punjab. The havoc created by this scourge was surely a stern reminder of the day of judgement. With an average of thirty to forty thousand people dying every week, thousands of villages, towns, and cities were deserted overnight. The prophecy had a positive impact on right-minded people, a lot of them joined the Community.
The Promised Messiah(as) announced that all his true followers will be saved and will not die of this deadly disease. Indeed God Almighty saved his Messenger, his family and all of his faithful followers as foretold in the following prophecy:
“I will protect all those who are within the periphery of your house”. (Kashtee Nooh, page 4, October 5th, 1902)
