Egypt's Crops are Destroyed by Locusts
As often as they were troubled grievously, they appealed to Moses thus: "0 Moses! Invoke your Lord for us because of His Promise to you. If you will remove the punishment fromus, we indeed shall believe in you, and we shall let the children of Israel go with you." Surah 7: 134
Moses prayed to his Lord and He relieved the suffering caused by the flood. The surging water ceased and withdrew from the land, and it became cultivatable. But when Moses bade them to fulfill their promise to release the children of Israel, they did not respond.
Then Allah sent swarms of locusts which ate whatever crops they had grown. The people hurried to Moses, asking him to invoke Allah to remove this affliction and promising they would send the children of Israel with him this time. The locusts departed, but they did not fulfill their promise.
Egypt Becomes Infested with Lice
Then another sign came, the sign of lice, which spread amongst the Egyptians, carrying diseases. Their refuge to Moses and their promise to him were repeated. His prayer to Allah was repeated and so, too, their breach of promise, as usual.
Egypt Becomes Infested with Frogs
A sign of frogs was revealed. The land suddenly filled with frogs. They jumped on the food of the Egyptians, shared their houses, and distressed them greatly. The Egyptians went to Moses again, promising him to release the children of Israel. He prayed to his Lord, and Allah relieved them of the problem of the frogs, but they again broke their promise.
Then the last sign was revealed, the sign of blood. The Nile water was changed into blood. When Moses and his people drank the water, it was, for them, ordinary water. However, if any Egyptian filled his cup with the water, he discovered his cup full of blood. They hurried to Moses as usual, but as soon as everything returned to normal, they turned their backs on Allah.
Allah's Punishments on the Disbelievers - Qur'anic
Almighty Allah said: And indeed We punished the people of Pharaoh with years of drought and shortness of fruits (crops, etc.), that they might remember (take heed). But whenever good came to them, they said: "Ours is this." And if evil afflicted them, they ascribed it to euil omens connected with Moses and those with him. Be informed! Verily, their evil omens are with Allah but most of them know not. They said (to Moses): "Whatever Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) you may bring to us, to work therewith your sorcery on us, we shall never believe in you." So We sent on them: the flood, the locusts, the lice, the frogs, and the blood: (as a succession of) manifest signs, yet they remained arrogant, and they were of those people who were Mujrimeen (criminals, polyt heists, sinners, etc.) Surah 7: 130-133
Almighty Allah also said: But when We removed the punishment from them to a fixed term, which they had to reach, behold! They broke their word! Surah 7: 135
Moses's Story - Condensed and Qur'anic
Pharaoh became ruder and more arrogant. He proclaimed to his people: "Pharaoh is the only god. Has he not the kingdom of Egypt and rivers flowing under it?" He declared that Moses was a liar, a magician, and a poor man who did not wear even one bracelet of gold. Almighty Allah declared: And indeed We did send Moses with Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) to Pharaoh and his chiefs (inviting them to Allah's Religion of Islam). He said: "Verily, I am a Messenger of the Lord of the Alamin (mankind, jinn and all that exists).
But when he came to them with Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) behold! They laughed at them. And not an Ayah (sign etc.) We showed them but it was greater than its fellow, and We seized them with torment, in order that they might turn from their polytheism to Allah's Religion (Islamic Monotheism).
And they said (to Moses): "0 you sorcerer! Invoke your Lord for us according to what He has covenanted with you. Verily, we shall guide ourselves (aright)."
But when We removed the torment from them, behold! They broke their covenant (that they will believe if We remove the torment for them).
And Pharaoh proclaimed among his people, saying: '0 my people! Is not mine the dominion of Egypt, and these rivers flowing underneath me. See you not then? Am I not better than this one (Moses), who is Mahin has no honor nor any respect, and is weak and despicable and can scarcely express himself clearly? Why then are not golden bracelets bestowed on him, or angels sent along with him?"
Thus he (Pharaoh) befooled and misled his people, and they obeyed him. Verily, they were Fasiqeen (rebellious, disobedient to Allah).
So when they angered Us, We punished them, and drowned them all. And We made them a precedent (as a lesson for those coming after them), and an example to later generations. Surah 43: 46-56
