Nation of Prophet Nuh-Naoh عليه السلام
The nation of Prophet Noah (عليه السلام) was a very arrogant and disobedient nation who used to worship idols. They had no fear of Allah سبحانه وتعالى. Prophet Noah (عليه السلام) stayed with them for many centuries and taught them to worship and obey Allah سبحانه وتعالى alone and to fear from the accountability of the Day of Judgement. The people of his nation refused to accept him as a true messenger of Allah سبحانه وتعالى and completely ignored his teachings. They also demanded from him to bring forth the promised torment of Allah سبحانه وتعالى.They threatened to kill him if he would not stop his preaching and made plots to do so. Very few people became believers to his teachings over a long period of time. Successive generations continued to produce non-believers and infidels. Ultimately, the Prophet Noah (عليه السلام) prayed to Allah سبحانه وتعالى to destroy the nation of non-believers as he saw no prospective of change among them or their future generations.
At this stage, Allah سبحانه وتعالى directed Prophet Noah (عليه السلام) to prepare an ark under His direct guidance. The people of his nation used to make a mockery of him when he was preparing the ark. When the ark was complete, Allah سبحانه وتعالى asked Prophet Noah (عليه السلام) to take his followers and one pair of male and female from each animal species to his ark. The great flood then followed with water coming out of the earth and from the skies. Everybody out of the ark was thus destroyed in the flood while Prophet Noah (عليه السلام) and his followers were saved.
In this story of Prophet Noah (عليه السلام) and his nation, there are many lessons and signs for people of understanding.
