Surat Saba (Sheba) - سبإ

قُلْ إِنَّمَآ أَعِظُكُم بِوَٰحِدَةٍ أَن تَقُومُوا۟ لِلَّهِ مَثْنَىٰ وَفُرَٰدَىٰ ثُمَّ تَتَفَكَّرُوا۟ مَا بِصَاحِبِكُم مِّن جِنَّةٍ إِنْ هُوَ إِلَّا نَذِيرٌ لَّكُم بَيْنَ يَدَىْ عَذَابٍ شَدِيدٍ ﴿٤٦﴾

Say: I exhort you only to one thing, that rise up for Allah's sake in twos and singly, then ponder: there is no madness in your fellow-citizen; he is only a warner to you before a severe chastisement.
