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
