أَلَآ إِنَّ لِلَّهِ مَا فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۗ أَلَآ إِنَّ وَعْدَ ٱللَّهِ حَقٌّ وَلَـٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ
Translations
Unquestionably, to Allah belongs whatever is in the heavens and the earth. Unquestionably, the promise of Allah is truth, but most of them do not knowC'est à Allah qu'appartient, certes, tout ce qui est dans les cieux et sur la terre. Certes, la promesse d'Allah est vérité. Mais la plupart d'entre eux ne (le) savent pas.Tafsir
The control of whatever is in the heavens and earth is only Allah’s. Allah’s promise of punishment for the disbelievers will undoubtedly occur, but most of them do not know that and are therefore in doubt.
Read Ibn Kathir (Ibn Kathir (abridged, English))
No doubt, surely, all that is in the heavens and the earth belongs to Allah. No doubt, surely, Allah's promise is true. But most of them know not (55)It is He Who gives life, and causes death, and to Him you (all) shall return.) Allah is the Owner of the heavens and earth. His promise is true and is indeed going to be fulfilled. He is the One Who gives life and causes death. To Him is the return of everyone, and He is the One who has the power over that, and the One Who knows everything about every creature; its deterioration, and where every speck of it has gone, be it land, oceans or otherwis (56)
