Noah's Ark And Number Of Animals
The Qur’an higlights the event of Nuh (AS) sent as Rasuul to a nation . When judgment is done after Rasuul completes Hujjat, the warned nation is then to be punished. Because it would be against justice for Allah to punish everyone on the earth just because one nation to which a Rasuul was sent. Because to punish the entire world, you would have to send a Rasuul to warn the entire world first but instead only a single nation (i.e of Nuh (AS)) was warned and therefore, by justice, only they must be punished because only they were warned. That is why the punishment was for a nation and for that Nuh (AS) and the believers only took what they needed to start a new life in the land (i.e domestic animals) that Allah gave them after the punishment of those that were warned and did not listen.
Also Quran is the only authentic book remaining in its original language that is still alive today. Bible is mostly not a direct word of Allah. Bible has over 60 distinct versions that are dramatically different. Original language of Bible is not alive and there are no authentic remaining copy of Bible nor was it memorized by thousands of people generation after generations like Quran. Also, history documents deliberate changes in Bible by some kings and other powerful person.
