أَخْبَرَنَا كُلْثُومٌ، نا عَطَاءٌ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: " لَا شِغَارَ فِي الْإِسْلَامِ وَهُوَ أَنْ تُنْكَحَ الْمَرْأَةُ بِصَدَاقِ الْأُخْرَى يَقُولُ: أَنْكِحْنِي وَأُنْكِحُكَ بِغَيْرِ صَدَاقٍ فَذَاكَ الشَّغَارُ ".
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "There is no Shighar (a type of marriage) in Islam." And that is when a woman is married in exchange for the dowry of another woman, he says: Marry her to me and I will marry her to you, and there will be no dowry; this is called Shighar.
