فَإِذَا جَاءتْهُمُ الْحَسَنَةُ قَالُواْ لَنَا هَـذِهِ وَإِن تُصِبْهُمْ سَيِّئَةٌ يَطَّيَّرُواْ بِمُوسَى وَمَن مَّعَهُ أَلا إِنَّمَا طَائِرُهُمْ عِندَ اللّهُ وَلَـكِنَّ أَكْثَرَهُمْ لاَ يَعْلَمُونَ
[7:131]
But when good befell them they said: This is due to us; and when evil afflicted them, they attributed it to the ill-luck of Musa and those with him; surely their evil fortune is only from Allah but most of them do not know.
But when good (times) came, they said, "This is due to us;" When gripped by calamity, they ascribed it to evil omens connected with Moses and those with him! Behold! in truth the omens of evil are theirs in Allah's sight, but most of them do not understand!
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.
