Aga Shaykh Ali Muwahhid, who traveled to Larsitan as a missionary of Islam and to propagate religion, has recounted as follows on his return:

I was staying at Dasht Merv plateau. On ninth Muharram some persons reported that previous night a light similar to moonlight was seen from a trunk of a berry tree, which is at a distance of four farsakhs (24 kilometers) from there and some natives of that area even went to see it from close.

The following day, that is the Day of Ashura, they again reported that tonight no light was seen, but blood dripped from that tree. They brought a piece of paper having some drops of blood from that tree.

Some Sunni residents of that place, after witnessing that blood started cursing Yazid and the killers of Husayn and participated in the mourning rituals of Imam Husayn ('a) along with Shia.

On Ashura Day there have been instances in different parts of the world, where blood was seen dripping from trees and non-living objects thus proving the greatness of those personages. There is consensus of Shia and some Sunni historians on this. For more details you may refer to the book of Shifaus Sudoor. One such incident is mentioned in Riyadh ul-Quds about a tree, which is situated in Zarrabad in Qazwin.

If the eyes of the world had wept on him freely, a flood of bloody tears would have exceeded even the height of the hall of Karbala. (Persian couplet)

We shall narrate two more stories to support this point.
