quran:38:20 –

And We strengthened his kingdom and gave him wisdom and discernment in speech.  

And We strengthened his Kingdom, We reinforced it with guards and hosts: every night there thirty thousand men would be standing guard at his sanctuary; and gave him wisdom, prophethood and sound judgement in ˹all˺ matters, and decisive speech, ˹the ability to formulate˺ a satisfactory statement ˹for a decision˺ in any endeavour.
القرآن:٣٨:٢٠ –

وَشَدَدْنَا مُلْكَهُ وَآتَيْنَاهُ الْحِكْمَةَ وَفَصْلَ الْخِطَابِ  

{وشددنا ملكه} قوَّيناه بالجرس والجنود وكان يحرس محرابه في كل ليلة ثلاثون ألف رجل {وآتيناه الحكمة} النبوة والإصابة في الأمور {وفصل الخطاب} البيان الشافي في كل قصد.
