There was a pebble, which the Messenger of Allah (s.a.w.a.)
picked up on the day of Battle of Hunain and it recited divine praise.
The Prophet ordered it to divide into three parts. So it divided into
three portions and each portion recited divine praise.
Also, there were stones, which saluted the Prophet and spoke to
him.
There were also rocks, on which Ameerul Momineen (a.s.) hit
the staff of the Prophet and a hundred she camels emerged from it
and in this way, he fulfilled the promise of Prophet to that Arab. This
itself is like the miracle of Prophet Salih (a.s.): that a camel appeared
from the mountain by permission of Allah.
Salihul Momineen [most righteous of believers] that is Ameerul
Momineen (a.s.) also did that and instead of one camel, a hundred
camels emerged.
In the same way, it is narrated that pebbles spoke up in the
blessed hands of Ameerul Momineen (a.s.) as follows: “There is no
god, except Allah; Muhammad is messenger of Allah. I approve
Allah as Lord, Muhammad as prophet and Ali Ibne Abi Talib (a.s.)
as Wali.”
Also there is the incident of those pebbles, which turned into
gems upon the intention of Ameerul Momineen (a.s.).
Pebbles, which Imam Zamana (a.s.) gave to someone, and due
to the intention of His Eminence, they turned into gold.
Incident of a person, who was indebted and when Ameerul
Momineen (a.s.) ordered him to pick up in his presence a stone and
lump of mud, by the intention of His Eminence that stone and lump
turned into pure gold and he repaid his debts as is also mentioned in
its place.
