Mishkat al-Masabih 13 Marriage كتاب النكاح 123

وَعَنْ جَابِرٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ أَعْطَى فِي صَدَاقِ امْرَأَتِهِ مِلْءَ كَفَّيْهِ سَوِيقًا أَوْ تَمْرًا فَقَدِ اسْتحلَّ» . رَوَاهُ أَبُو دَاوُد

Jabir reported God’s Messenger as saying, “If anyone gives as a dower to his wife two handfuls of flour or dates he has made her lawful for him.” Abu Dawud transmitted it.
