A man consummating the marriage with his wife before giving her anything
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا الْهَيْثَمُ بْنُ جَمِيلٍ، حَدَّثَنَا شَرِيكٌ، عَنْ مَنْصُورٍ، - أَظُنُّهُ - عَنْ طَلْحَةَ، عَنْ خَيْثَمَةَ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ أَمَرَهَا أَنْ تُدْخِلَ عَلَى رَجُلٍ امْرَأَتَهُ قَبْلَ أَنْ يُعْطِيَهَا شَيْئًا .
It was narrated from 'Aishah that: the Messenger of Allah (ﷺ) told her to take a woman to her husband before he had given her anything (i.e. bridal-money). (Da' if)
