And Allah created you from the soil then from the sperm, then He made you pairs, and no female carries or lays down but with His knowledge. And nothing is lengthened in life nor anything is reduced from one’s life, but (the length of life is written) in a record. This is certainly easy for Allah.
Allah (SWT) has fixed the length of everyone’s life 3:145,3:154. He it is Who has made two types of waters, water on landmasses and underground water are normally sweet and pleasant to drink whereas sea and ocean waters are saltish. It is again Allah (SWT) Who makes all heavenly bodies weighing thousands of tones, float and move in space.
