فَإِذَا So when fa-idhā you recite qarata the Quran l-qur'āna seek refuge fa-is'taʿidh in Allah bil-lahi from mina the Shaitaan l-shayṭāni the accursed l-rajīmi
So when you recite the Qur’ān, [first] seek refuge in Allāh from Satan, the expelled [from His mercy].
إِنَّهُۥ Indeed he innahu not laysa for him lahu (is) any authority sul'ṭānun on ʿalā those who alladhīna believe āmanū and upon waʿalā their Lord rabbihim they put their trust yatawakkalūna
Indeed, there is for him no authority over those who have believed and rely upon their Lord.
إِنَّمَا Only innamā his authority sul'ṭānuhu (is) over ʿalā those who alladhīna take him as an ally yatawallawnahu and those who wa-alladhīna [they] hum with Him bihi associate partners mush'rikūna
His authority is only over those who take him as an ally and those who through him associate others with Allāh.
