الآية رقم (108) - يَسْتَخْفُونَ مِنَ النَّاسِ وَلاَ يَسْتَخْفُونَ مِنَ اللّهِ وَهُوَ مَعَهُمْ إِذْ يُبَيِّتُونَ مَا لاَ يَرْضَى مِنَ الْقَوْلِ وَكَانَ اللّهُ بِمَا يَعْمَلُونَ مُحِيطًا

(108) - {They conceal [their evil intentions and deeds] from the people, but they cannot conceal [them] from Allah, and He is with them [in His knowledge] when they spend the night in such as He does not accept of speech. And ever is Allah, of what they do, encompassing.}

They concealed their evil deeds and intentions from the people because they feared that it would be said that a Muslim is a thief and the Jew is innocent, whereas the priority is to fear Allah (swt).
