The Night Journey
وَرَبُّكَ أَعْلَمُ بِمَن فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۗ وَلَقَدْ فَضَّلْنَا بَعْضَ ٱلنَّبِيِّـۧنَ عَلَىٰ بَعْضٍ ۖ وَءَاتَيْنَا دَاوُۥدَ زَبُورًا
And your Lord is most knowing of whoever is in the heavens and the earth. And We have made some of the prophets exceed others [in various ways], and to David We gave the book [of Psalms].

وَقُل لِّعِبَادِى يَقُولُوا۟ ٱلَّتِى هِىَ أَحْسَنُ ۚ إِنَّ ٱلشَّيْطَـٰنَ يَنزَغُ بَيْنَهُمْ ۚ إِنَّ ٱلشَّيْطَـٰنَ كَانَ لِلْإِنسَـٰنِ عَدُوًّا مُّبِينًا
And tell My servants to say that which is best. Indeed, Satan induces [dissension] among them. Indeed Satan is ever, to mankind, a clear enemy.
رَّبُّكُمْ أَعْلَمُ بِكُمْ ۖ إِن يَشَأْ يَرْحَمْكُمْ أَوْ إِن يَشَأْ يُعَذِّبْكُمْ ۚ وَمَآ أَرْسَلْنَـٰكَ عَلَيْهِمْ وَكِيلًا
Your Lord is most knowing of you. If He wills, He will have mercy upon you; or if He wills, He will punish you. And We have not sent you, [O Muhammad], over them as a manager.
قُلِ ٱدْعُوا۟ ٱلَّذِينَ زَعَمْتُم مِّن دُونِهِۦ فَلَا يَمْلِكُونَ كَشْفَ ٱلضُّرِّ عَنكُمْ وَلَا تَحْوِيلًا
Say, "Invoke those you have claimed [as gods] besides Him, for they do not possess the [ability for] removal of adversity from you or [for its] transfer [to someone else]."
أُو۟لَـٰٓئِكَ ٱلَّذِينَ يَدْعُونَ يَبْتَغُونَ إِلَىٰ رَبِّهِمُ ٱلْوَسِيلَةَ أَيُّهُمْ أَقْرَبُ وَيَرْجُونَ رَحْمَتَهُۥ وَيَخَافُونَ عَذَابَهُۥٓ ۚ إِنَّ عَذَابَ رَبِّكَ كَانَ مَحْذُورًا
Those whom they invoke seek means of access to their Lord, [striving as to] which of them would be nearest, and they hope for His mercy and fear His punishment. Indeed, the punishment of your Lord is ever feared.
