78:14 and We bring down from dripping clouds water in abundance,—

78:14 The word mu‘sirāt, derived from the verbal root ‘asara, denotes to squeeze something, to press (as juices from grapes). The use of the word mu‘sirāt meaning to squeeze out rain (from cloud) or emit rain by pressing appropriately points at the cause of rain when clouds are ‘compressed’ or ‘thickened’. The Qur’ān disclosed this brilliant scientific truth long before modern science adequately understood the physics behind formation of rain.
