فَإِذَا جَآءَتْهُمُ ٱلْحَسَنَةُ قَالُوا۟ لَنَا هَٰذِهِۦ ۖ وَإِن تُصِبْهُمْ سَيِّئَةٌۭ يَطَّيَّرُوا۟ بِمُوسَىٰ وَمَن مَّعَهُۥٓ ۗ أَلَآ إِنَّمَا طَٰٓئِرُهُمْ عِندَ ٱللَّهِ وَلَٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ
But whenever good befell them, they said: This is ours; and whenever evil smote them they ascribed it to the evil auspices of Moses and those with him. Surely their evil auspice was only with Allah. But most of them knew not.
