عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا يَخْطُبُ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ وَلَا تُنْكَحُ الْمَرْأَةُ عَلَى عَمَّتِهَا وَلَا عَلَى خَالَتِهَا وَلَا تَسْأَلُ طَلَاقَ أُخْتِهَا لِتَكْتَفِئَ مَا فِي صَحْفَتِهَا وَلْتَنْكِحْ فَإِنَّمَا لَهَا مَا كَتَبَ اللَّهُ لَهَا
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: A man should not propose to a woman to whom his brother has already proposed; a woman should not be married in the presence of her paternal or maternal aunt; no woman should ask for her sister to be divorced so that she may pour what is in her sister’s cup into her own; she should marry, for she will receive whatever Allah Almighty has decreed for her.
