So We sent (plagues) on them wholesale death Locusts Lice Frogs and Blood: signs openly Self-explained; but they were steeped in arrogance a people given to sin. 1090 1091
Tufan = a widespread calamity, causing wholesale death and destruction. It may be a flood, or a typhoon, or an epidemic, among men or cattle. Perhaps the last is meant, if we may interpret by the Old Testament story. See also Exod. ix. 3, 9, 15; xii. 29.
In xvii. 101, the reference is to nine Clear Signs. These are: (1) the Rod (vii. 107), (2) the Radiant Hand (vii. 108), (3) the years of drought or shortage of water (vii, 130), (4) short crops (vii. 130), and the five mentioned in this verse, viz., (5) epidemics among men and beasts, (6) locusts, (7) lice, (8) frogs, and (9) the water turning to blood.
