Surah Saba, verse 48

۞ قُلْ إِنَّمَآ أَعِظُكُم بِوَٰحِدَةٍ ۖ أَن تَقُومُوا۟ لِلَّهِ مَثْنَىٰ وَفُرَٰدَىٰ ثُمَّ تَتَفَكَّرُوا۟ ۚ مَا بِصَاحِبِكُم مِّن جِنَّةٍ ۚ إِنْ هُوَ إِلَّا نَذِيرٌۭ لَّكُم بَيْنَ يَدَىْ عَذَابٍۢ شَدِيدٍۢ ﴿٤٦﴾

Say, "I only advise you of one [thing] - that you stand for Allāh, [seeking truth] in pairs and individually, and then give thought." There is not in your companion any madness. He is only a warner to you before a severe punishment.

قُلْ مَا سَأَلْتُكُم مِّنْ أَجْرٍۢ فَهُوَ لَكُمْ ۖ إِنْ أَجْرِىَ إِلَّا عَلَى ٱللَّهِ ۖ وَهُوَ عَلَىٰ كُلِّ شَىْءٍۢ شَهِيدٌۭ ﴿٤٧﴾

Say, "Whatever payment I might have asked of you - it is yours. My payment is only from Allāh, and He is, over all things, Witness."

قُلْ جَآءَ ٱلْحَقُّ وَمَا يُبْدِئُ ٱلْبَـٰطِلُ وَمَا يُعِيدُ ﴿٤٩﴾

Say, "The truth has come, and falsehood can neither begin [anything] nor repeat [it]."

قُلْ إِن ضَلَلْتُ فَإِنَّمَآ أَضِلُّ عَلَىٰ نَفْسِى ۖ وَإِنِ ٱهْتَدَيْتُ فَبِمَا يُوحِىٓ إِلَىَّ رَبِّىٓ ۚ إِنَّهُۥ سَمِيعٌۭ قَرِيبٌۭ ﴿٥٠﴾

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."
