He says that if you could see what your dead have seen, you would be terrified, confused and agitated, and you would listen to the truth and act upon it. What they have witnessed is still veiled from you, but the veil is close to being lifted. Those who have eyes of insight and ears that hear have already been shown and told, and whoever truly seeks guidance has already been guided. Lessons have called out loudly to you and threats have warned you. After the heavenly messengers (angels), it is human messengers who convey Allah’s message, and the guidance that comes from his own tongue is in reality Allah’s message reaching you.
