﴿ وَشَدَدْنَا مُلْكَهُۥ وَءَاتَيْنَٰهُ ٱلْحِكْمَةَ وَفَصْلَ ٱلْخِطَابِ ﴾

“And We streng­thened his dominion, and bestowed upon him wisdom and sagacity in judgment.”

(We made his kingdom strong) with guardsmen; his royal chamber was guarded every night by 30,000 men (and gave him wisdom) prophethood (and decisive speech) and judgement; he never stumbled in his speech when he judged between people. In his judgement proof was required from the claimant while an oath was required from the defendant.
