Tafsir of Al-Qasas 28:87

وﻻ يصدنك عن آيات الله بعد إذ أنزلت إليك

And let them not turn you away from the Ayat of Allah after they have been sent down to you. meaning, `Do not let their opposition to you affect you or put people off from following your way; do not worry about that or pay any attention to it, for Allah will make your word supreme, will support your religion and will make the Message with which He has sent you prevail over all other religions.' So He says:

وادع إلى ربك

and invite to your Lord, to worship your Lord Alone, with no partners or associates,

وﻻ تكونن من المشركين

and be not of idolators
