(18) باب فِي كَرَاهِيَةِ أَنْ يَخْطُبَ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ
Narrated Abdullah ibn Umar:
The Prophet (ﷺ) said: One of you must not ask a woman in marriage when his brother has done so already, and one of you must not sell (his own goods) when his brother has already sold (his goods) except with his permission.
