AHMAD 7248:
from Abū Hurayrah —
[Machine] The Prophet ﷺ prohibited selling an item that someone else already intended to buy, or competing with someone in a transaction, or a man proposing marriage to a woman who has already been proposed to by his brother, or selling something that belongs to his brother. A woman should not ask her sister for a divorce just to take what is in her dowry or her utensils; instead, she should marry, for her sustenance is from Allah.

عن ابو هريره —
أَنَّ النَّبِيَّ ﷺ نَهَى أَنْ يَبِيعَ حَاضِرٌ لِبَادٍ أَوْ يَتَنَاجَشُوا أَوْ يَخْطُبَ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ أَوْ يَبِيعَ عَلَى بَيْعِ أَخِيهِ وَلَا تَسْأَلِ الْمَرْأَةُ طَلَاقَ أُخْتِهَا لِتَكْتَفِئَ مَا فِي صَحْفَتِهَا أَوْ إِنَائِهَا وَلْتَنْكِحْ فَإِنَّمَا رِزْقُهَا عَلَى اللهِ
