16/6. Chapter:
The prohibition of proposing marriage when one's brother has already proposed, unless he gives permission or gives up the idea
Sahih Muslim
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ الأَعْلَى، ح وَحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، جَمِيعًا عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ . مِثْلَهُ غَيْرَ أَنَّ فِي حَدِيثِ مَعْمَرٍ " وَلاَ يَزِدِ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ " .
A hadith like this has been narrated on the authority of Zuhri with the same chain of transmitters but with a slight alteration.
