Abu Huraira (Allah be pleased with him) reported that Messenger of Allah ﷺ forbade the combining of a woman in marriage with her father's sister, or with her mother's sister, or that a woman should ask for divorce for her sister in order to deprive her of what belongs to her. Allah, the Exalted'and Majestic, is her Sustainer too.
نَهَى رَسُولُ اللَّهِ ﷺ أَنْ تُنْكَحَ الْمَرْأَةُ عَلَى عَمَّتِهَا أَوْ خَالَتِهَا أَوْ أَنْ تَسْأَلَ الْمَرْأَةُ طَلاَقَ أُخْتِهَا لِتَكْتَفِئَ مَا فِي صَحْفَتِهَا فَإِنَّ اللَّهَ ﷻ رَازِقُهَا
