فَإِذَا جَآءَتْهُمُ ٱلْحَسَنَةُ قَالُوا۟ لَنَا هَـٰذِهِۦ ۖ وَإِن تُصِبْهُمْ سَيِّئَةٌ يَطَّيَّرُوا۟ بِمُوسَىٰ وَمَن مَّعَهُۥٓ ۗ أَلَآ إِنَّمَا طَـٰٓئِرُهُمْ عِندَ ٱللَّهِ وَلَـٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ

But when good [i.e., provision] came to them, they said, "This is ours [by right]." And if a bad [condition] struck them, they saw an evil omen in Moses and those with him. Unquestionably, their fortune is with Allāh, but most of them do not know.

then, when something good came their way, they said, ‘This is our due!’. When something bad came, they ascribed it to the evil omen of Moses and those with him, but their ‘evil omen’ was really from God, though most of them did not realize it.
— M. A. S. Abdel Haleem
But whenever good came to them, they said: "Ours is this." And if evil afflicted them, they ascribed it to evil omens connected with Mûsâ (Moses) and those with him. Be informed! Verily, their evil omens are with Allâh but most of them know not.
