﴿ فَأَرْسَلْنَا عَلَيْهِمُ ٱلطُّوفَانَ وَٱلْجَرَادَ وَٱلْقُمَّلَ وَٱلضَّفَادِعَ وَٱلدَّمَ ءَايَٰتٍۢ مُّفَصَّلَٰتٍۢ فَٱسْتَكْبَرُوا۟ وَكَانُوا۟ قَوْمًۭا مُّجْرِمِينَ ﴾

“Thereupon We let loose upon them floods, and [plagues of] locusts, and lice, and frogs, and [water turning into] blood -distinct signs [all]: but they gloried in their arrogance, for they were people lost in sin.”

So We unleashed upon them the flood of water which penetrated their houses and which for seven days would come up to people’s necks as they sat; and the locusts which consumed their crops and fruits likewise engulfing them for seven days; and the lice al-qummal is like al-sūs ‘woodworm’ or al-qurād ‘ticks’ which would follow and consume what the locusts left behind; and the frogs such that they infested their houses and food supplies; and the blood flowing in their water distinct clear signs but they were too scornful to believe in them and were a sinful folk.
