The incident of Ohud provided a ground for the enemies of Islam to spray poisons, which caused the revelation of several verses, in order to neutralize such poisonous propagandas: ``O, you who believe! Be not like the unbelievers who said in their brothers, when they travelled for an expedition or were engaged in a fighting in the way of Allah; if they had stayed with us at home, they would not have died or been killed there!'' Such wrong suggestions or ideas, is due to want of faith, and nothing can happen without God's will, because it is Allah that gives life and death, and sees whatever we do.
