The document discusses two topics from the Quran: the weight of clouds and the proportion of rain. It references several Quranic verses from Surat Al-'A`rāf and Surat Ar-Ra`d that describe how Allah has made the clouds heavy and given the ability to cause rain. Another verse from Surat Az-Zukhruf is referenced that discusses how Allah has apportioned the rain and knows what goes into the earth and what comes out of it.
