قُلْ إِن ضَلَلْتُ فَإِنَّمَآ أَضِلُّ عَلَىٰ نَفْسِى ۖ وَإِنِ ٱهْتَدَيْتُ فَبِمَا يُوحِىٓ إِلَىَّ رَبِّىٓ ۚ إِنَّهُۥ سَمِيعٌ قَرِيبٌ
Say, "If I should err, I would only err against myself. But if I am guided, it is by what my Lord reveals to me. Indeed, He is Hearing and near."

قُلْ جَآءَ ٱلْحَقُّ وَمَا يُبْدِئُ ٱلْبَـٰطِلُ وَمَا يُعِيدُ
Say, "The truth has come, and falsehood can neither begin [anything] nor repeat [it]."
وَلَوْ تَرَىٰٓ إِذْ فَزِعُوا۟ فَلَا فَوْتَ وَأُخِذُوا۟ مِن مَّكَانٍ قَرِيبٍ
And if you could see when they are terrified but there is no escape, and they will be seized from a place nearby.
وَقَالُوٓا۟ ءَامَنَّا بِهِۦ وَأَنَّىٰ لَهُمُ ٱلتَّنَاوُشُ مِن مَّكَانٍۭ بَعِيدٍ
And they will [then] say, "We believe in it!" But how for them will be the taking [of faith] from a place far away?
