﴿ وَٱللَّهُ يُرِيدُ أَن يَتُوبَ عَلَيْكُمْ وَيُرِيدُ ٱلَّذِينَ يَتَّبِعُونَ ٱلشَّهَوَٰتِ أَن تَمِيلُوا۟ مَيْلًا عَظِيمًۭا ﴾

“And God wants to turn unto you in His mercy, whereas those who follow [only] their own lusts want you to drift far away from the right path.”

(And Allah wishes to turn to you in mercy) He wishes to overlook your transgression when He made adultery and marrying your sisters, from the father's side, forbidden for you; (but those who follow vain desires) i.e. adultery and marrying their sisters from their fathers' side, namely, the Jews (would have you go tremendously astray) commit a serious error by marrying your sisters, from the father's side, by claiming that it is lawful in their Scripture.
