[Machine] I heard the Messenger of Allah ﷺ say, "It is not permissible for a Muslim to propose marriage to his brother's betrothed until he withdraws, nor is it permissible for him to sell to his brother's sale until he withdraws."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَا يَحِلُّ لِامْرِئٍ مُسْلِمٍ يَخْطُبُ عَلَى خِطْبَةِ أَخِيهِ حَتَّى يَتْرُكَ وَلَا يَبِيعُ عَلَى بَيْعِ أَخِيهِ حَتَّى يَتْرُكَ  

[Machine] "I heard the Messenger of Allah ﷺ say, 'It is not permissible for a believer in Allah and the Last Day to sell a transaction that has already been sold by his brother until he leaves it.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «لَا يَحِلُّ لِامْرِئٍ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَنْ يَبِيعَ عَلَى بَيْعِ أَخِيهِ حَتَّى يَتْرُكَهُ»
