قُلْ إِنَّمَا أَعِظُكُم بِوَاحِدَةٍ أَن تَقُومُوا لِلَّهِ مَثْنَى وَفُرَادَى ثُمَّ تَتَفَكَّرُوا مَا بِصَاحِبِكُم مِّن جِنَّةٍ إِنْ هُوَ إِلَّا نَذِيرٌ لَّكُم بَيْنَ يَدَيْ عَذَابٍ شَدِيدٍ
﴿٤٦﴾
سورة سبإ
(34/46) Say: “I sermon you only one thing. Rise up (stand up) for Allah in pairs and singly, then ponder (reflect)”. There is no madness in your owner (companion). He is only a Warner to you for the severe torment before you (that will come to you).
Surah Saba
