حُرِّمَتْ عَلَيْكُمْ أُمَّهَاتُكُمْ وَبَنَاتُكُمْ وَأَخَوَاتُكُمْ وَعَمَّاتُكُمْ
And the wives of your genetic sons, and marrying two sisters simultaneously
إسلام ويب
Consequently, the Messenger stated that his marriage to Umm Salamah was the real reason behind that prohibition
إسلام ويب
But when they are married, if they commit fornication, then inflict upon them half the penalty for free women; that is for whomsoever of you fears wrong; but that you should have patience is better for you, for Allah is Forgiving and Merciful
They all stated that taking two sisters as rival wives is prohibited, and that whoever embraces Islam while married to two sisters at the same time is given the choice to keep one of them and divorce the other
It means that these two Ayat encompass these types of women, whether the marriage was consummated or not, and there is a consensus on this ruling You are forbidden to marry the wives of your own sons and to marry two sisters at the same time without any adverse affect to the such relations of the past

Forbidden unto you are your mothers, and your daughters, and your sisters, and your father's sisters, and your mother's sisters, and your brother's daughters and your sister's daughters, and your foster-mothers, and your foster-sisters, and your mothers-in-law, and your step-daughters who are under your protection born of your women unto whom ye have gone in - but if ye have not gone in unto them, then it is no sin for you to marry their daughters - and the wives of your sons who spring from your own loins.
