So We sent on them: the flood, the locusts, the Qummal, the frogs, and the blood; manifest signs, yet they remained arrogant, and they were of those people who were criminals. And when the punishment struck them, they said: "O Musa! Invoke your Lord for us because of His promise to you. If you remove the punishment from us, we indeed shall believe in you, and we shall let the Children of Israel go with you.'' But when We removed the punishment from them to a fixed term, which they had to reach, behold! they broke their word!) (7:133-135)
Above are a couple of verses from the Quran. What a person of common sense can learn from these verses are a few lessons, some of them could be: 1) the human history repeats itself with the changed names. Then Faroah was the oppressor and Israelis were the oppressed ones while now Israelis are the oppressors and the Muslims are the oppressed ones. 2) God is always with the weaker ones because most of the time they are on the Right Path or close to it. Then He was with the Israelis now He is with the Muslims! 3) Human beings try to inflict the same pains on others that they suffer from rather than trying to save others from the pains that they have tasted unless they follow the True Religion of their Creator, then only their hearts get filled with the light of the truth and mercy from the God and they show mercy to others. Until the creation of the State of Israel, Jews were pushed around and were persecuted by the Christians. As soon as they got the State of Israel, they started terrorizing and persecuting Muslims worse than what was done to them by others instead of realizing the pains and avoiding to inflict them on their fellow human beings.
Armageddon is around the corner. World is going to come to an end. Then wouldn't it be smart not to take the burden of others' sins by killing or torturing them to death? And wouldn't it be smart to try to save our souls rather than bodies? All the intelligence is being wasted on finding the ways of destroying other nations, religions, societies; trying to develop all the possible means of humiliating and torturing other human beings whose culture doesn't match ours. Shouldn't our efforts be directed to saving the humanity rather than destroying it? Shouldn't our time be spent on searching the truth for eternal peace rather than suppressing it and trying to distort it such that nobody can recognize it?
