عَن الرّبيع بنت معوذ بن عَفْرَاءَ قَالَتْ: جَاءَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَدَخَلَ حِينَ بُنِيَ عَلَيَّ فَجَلَسَ عَلَى فِرَاشِي كمجلسك مني فَجعلت جويرات لَنَا يَضْرِبْنَ بِالدُّفِّ وَيَنْدُبْنَ مَنْ قُتِلَ مِنْ آبَائِي يَوْمَ بَدْرٍ إِذْ قَالَتْ إِحْدَاهُنَّ: وَفِينَا نَبِيٌّ يَعْلَمُ مَا فِي غَدٍ فَقَالَ: «دَعِي هَذِهِ وَقُولِي بِالَّذِي كُنْتِ تَقُولِينَ» . رَوَاهُ الْبُخَارِيُّ

Ibn ‘Umar said God’s Messenger prohibited shighar, which means that a man gives his daughter in marriage on condition that the other gives his daughter to him in marriage without any dower being paid by either. In a version by Muslim he said, “There is no shighar in Islam."(Bukhari and Muslim.)
