عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ لَوْ أَنَّ رَجُلًا أَعْطَى امْرَأَةً صَدَاقًا مِلْءَ يَدَيْهِ طَعَامًا كَانَتْ لَهُ حَلَالًا
Narrated by Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: If a man gives a woman a handful of grain as dowry, she becomes lawful for him.
