تَبَارَكَ الَّذِي نَزَّلَ الْفُرْقَانَ عَلَىٰ عَبْدِهِ لِيَكُونَ لِلْعَالَمِينَ نَذِيرًا ﴿١﴾ الَّذِي لَهُ مُلْكُ السَّمَاوَاتِ وَالْأَرْضِ وَلَمْ يَتَّخِذْ وَلَدًا وَلَمْ يَكُن لَّهُ شَرِيكٌ فِي الْمُلْكِ وَخَلَقَ كُلَّ شَيْءٍ فَقَدَّرَهُ تَقْدِيرًا ﴿٢﴾
{بسم الله الرحمن الرحيم Blessed is He who sent down the Criterion upon His Servant that he may be to the worlds a warner - (1) He to whom belongs the dominion of the heavens and the earth and who has not taken a son and has not had a partner in dominion and has created each thing and determined it with [precise] determination. (2)}
