﴿ وَلَقَدْ صَدَّقَ عَلَيْهِمْ إِبْلِيسُ ظَنَّهُۥ فَٱتَّبَعُوهُ إِلَّا فَرِيقًۭا مِّنَ ٱلْمُؤْمِنِينَ ﴾

“Now, indeed, Iblis did prove that his opinion of them had been right: for [when he called them,] they followed him - all but some of the believers [among them].”

And verily Iblīs proved true read sadaqa or saddaqa his opinion of them that is of the disbelievers among them — the folk of Sheba — which was that by his tempting them to go astray they would follow him. So they followed him if the verb above is read sadaqa this would mean that ‘he was right in his opinion’ and if read saddaqa it would mean that ‘he found this opinion of his to be true’ — all except a group of the believers mina’l-mu’minīna the min ‘of’ is explicative not partitive in other words all except that group who were the believers they did not follow him.
