صَحِيحُ مُسْلِمٍ
Sahih Muslim 1412 d
The Book of Marriage
The prohibition of proposing marriage when one's brother has already proposed, unless he gives permission or gives up the idea
وَحَدَّثَنِيهِ أَبُو كَامِلٍ الْجَحْدَرِيُّ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا أَيُّوبُ، عَنْ نَافِعٍ، بِهَذَا الإِسْنَادِ.
A hadith like this has been reported on the authority of Nafi' with the same chain of transmitters.
