﴿ وَمَا كَانَ لَهُۥ عَلَيْهِم مِّن سُلْطَٰنٍ إِلَّا لِنَعْلَمَ مَن يُؤْمِنُ بِٱلْءَاخِرَةِ مِمَّنْ هُوَ مِنْهَا فِى شَكٍّۢ ۗ وَرَبُّكَ عَلَىٰ كُلِّ شَىْءٍ حَفِيظٌۭ ﴾

“And yet, he had no power at all over them: [for if We allow him to tempt man,] it is only to the end that We might make a clear distinction between those who [truly] believe in the life to come and those who are in doubt thereof: for thy Sustainer watches over all things.”

(And he) Satan (had no warrant) no power or the ability to impose his will (whatsoever against them) against the Children of Israel, (save) except to the measure (that We would know him who believeth in the Hereafter) that We know he who, in preeternity, believed in resurrection after death (from him who is in doubt thereof) from him who is in doubt about the coming of the Hour; (and thy Lord) O Muhammad (taketh note of all things) relating to their works.
