Noah Prays for the Disbeleivers' End
There came a day when Allah revealed to Noah that no others would believe. Allah inspired him not to grieve for them, at which point Noah prayed that the disbelievers be destroyed. He said: 'My Lord! Leave not one of the disbelievers on the earth. If you leave them, they will mislead Your slaves, and they will beget none but wicked disbelievers." Surah 71:27
Allah accepted Noah's prayer. The case was closed, and He passed His judgment on the disbelievers in the form of a flood. Allah the Exalted ordered His worshiper Noah to build an ark with His knowledge and instructions, and with the help of angels. Almighty Allah commanded: "And construct the ship under Our Eyes and with Our Inspiration, and address Me not on behalf of those who did wrong; they are surely to be drowned." Surah 11: 37

Noah Builds the Ark
Noah chose a place outside the city, far from the sea. He collected wood and tools and began to work day and night to build the ark. The people's mockery continued: "0 Noah! Does carpentry appeal to you more than prophethood? Why are you building an ark so far from the sea? Are you going to drag it to the water or is the wind going to carry it for you?" Noah replied: 'You will come to know who will be put to shame and suffer."
Allah the Almighty narrated: And as he was constructing the ship, whenever the chiefs of his people passed by him, they made a mockery of him. He said: "If you mock at us, so do we mock at you likewise for your mocking. And you will know who it is on whom will come a torment that will cover him with disgrace and on whom will fall a lasting torment. " Surah 11:38-392

The Flood Begins
The ship was constructed, and Noah sat waiting Allah's command. Allah revealed to him that when water miraculously gushed forth from the oven at Noah's house, that would be the sign of the start of the flood, the sign for Noah to act.
The terrible day arrived when the oven at Noah's house overflowed. Noah hurried to open the ark and summon the believers. He also took with him a pair, male and female, of every type of animal, bird and insect. Seeing him taking these creatures to the ark, the people laughed loudly: "Noah must have gone out of his head! What is he going to do with the animals?"
Almighty Allah narrated: (So it was) till then there came Our Command and the oven gushed forth (water like fountains from the earth). We said: "Embark therein, of each kind two (male and female), and your family, except him against whom the Word has already gone forth, and those who believe." And none believed him, except a few. Surah 11: 40

Description of the Flood
Water rose from the cracks in the earth; there was not a crack from which water did not rise. Rain poured from the sky in quantities never seen before on the earth. Water continued pouring from the sky and rising from the cracks; hour after hour the level rose. The seas and waves invaded the land. The interior of the earth moved in a strange way, and the ocean floors lifted suddenly, flooding the dry land. The earth, for the first time, was submerged.
