And if they see a miracle, they turn away and say, "Passing (54:2)

Almuntakhab Fi Tafsir Alquran Alkarim

Yet whenever they see an act of a miraculous nature serving to demonstrate Divine power, and omnipotence, authority and ground for belief, they look upon it as a secret and overmastering influence intended to shake their beliefs and they assert emphatically that such magic as the Messenger enchants them by, is doomed to failure and his hopes will be doomed to disappointment

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(54:2) (Regardless of any Signs these people see), they turn away and say: 'This is an ongoing sorcery.' *2

And if they see a miracle, they turn away and say, "Passing meaning

*2) The words sihr-um mustamirr of the Text can have several meanings: (1) That, God forbid, this magical illusion also is one of those magical performances that Muhammad (upon whom be Allah's peace and blessings) has been performing day and night; (2) that this certainly is a work of magic which has been performed with great expertise; and (3) that just as other works of magic have passed, so will this also pass without leaving any lasting effect behind.
