﴿ تِلْكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهَآ إِلَيْكَ ۖ مَا كُنتَ تَعْلَمُهَآ أَنتَ وَلَا قَوْمُكَ مِن قَبْلِ هَٰذَا ۖ فَٱصْبِرْ ۖ إِنَّ ٱلْعَٰقِبَةَ لِلْمُتَّقِينَ ﴾

“THESE ACCOUNTS of something that was beyond the reach of thy perception We [now] reveal unto thee, [O Muhammad: for] neither thou nor thy people knew them [fully] ere this. Be, then, [like Noah,] patient in adversity - for, behold, the future belongs to the God-conscious!”

(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.
