Another measure related with rain is about its falling speed. The minimum altitude of rain clouds is 1200 meters. When dropped from this height, an object having the same weight and size as a rain drop, would continuously accelerate and fall on the ground with a speed of 558 km/h........ Once again, Mr. Yahya is trying to impose his ideas on the text of the Qur'an. This passage is not talking about the speed on a raindrop, or the damage that it would cause if at fell at a faster speed!
