And when the messengers' time has come... meaning

*6) At several places in the Qur'an it has been stated that when the case of mankind will be presented before Allah on the Day of Resurrection, the Messenger of every nation will be called upon to testify that he had conveyed Allah's Messages intact to his people. This will be Allah's first and major argument against the culprits and the wicked people to prove that they were themselves responsible for their wrong attitude and conduct in life, for there had been no negligence on the part of Allah to show guidance and administer warnings . For instance, see AI-A`raf: 172, 173 and E.N.'s 134, 135, Az-Zumar: 69 and E.N. 80, Al-Mulk:8 and E.N. 14.
