قُلِ ٱللَّهُ أَعۡلَمُ بِمَا لَبِثُواْ ۖ لَهُۥ غَيۡبُ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِ ۖ أَبۡصِرۡ بِهِۦ وَأَسۡمِعۡ ۚ مَا لَهُم مِّن دُونِهِۦ مِن وَلِىٍّ وَلَا يُشۡرِكُ فِى حُكۡمِهِۦٓ أَحَدًا
Say: "Allah knows best how long they stayed: with Him is (the knowledge of) the secrets of the heavens and the earth: how clearly He sees, how finely He hears (everything)! They have no protector other than Him; nor does He share His Command with any person whatsoever.<br/>
Say: 'God is more knowledgeable of how long they tarried, [more knowledgeable] than those contending over this [issue] - and this [fact] has already been mentioned [above, verse 19]. To Him belongs the Unseen of the skies and the earth, that is, [to Him belongs] the knowledge thereof. How well He sees!, namely, God - this form is for [expressing] amazement [at something]. How well He hears!, likewise [for expressing amazement]. These two [expressions] are being used metaphorically. What is meant is that nothing can escape God's sight or hearing. They, the inhabitants of the skies and the earth, have no guardian, someone to assist [them], besides Him, and He makes none to share in His rule', for He is Independent, without need of a partner.
