(This is of the tidings of the Unseen) this is of the news of what has been hidden from you (which We inspire in thee) with which We sent Gabriel to you, O Muhammad, about the news of past nations. (Thou thyself knewest it not) i.e. you knew not the news of these past nations, (nor did thy folk (know it) before this) before the revelation of the Qur'an. (Then have patience) O Muhammad in the face of their denial and harm. (Lo! the sequel) the end result: victory and Paradise (is for those who ward off (evil)) ward off disbelief, idolatry and indecencies.
