Salam Alaikum
Attached is a picture of a stone that has the shape of a right hand with the index finger upright as if to indicate - la ilaha illa Allah, and the other remaining fingers are folded in. See the image for yourself. The amazing thing is - the stone is on mount Croagh Patrick in Westport, Co. Mayo, upon which hundreds of thousands of Christians climb the mountain annually bare footed in faith that their sins be forgiven. The mountain is more than 700 metres high. We climbed it for the craic and we spotted the stone on our way down, just after having performed salah on the mountain. As we tried to pick the stone to take it with us, we couldn't as the stone was thoroughly embedded into the soil. Subhan Allah.... wa la illaha illa Allah. Indeed there is no one worthy of worship except Allah.
Wassalam Alaikum
