وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَيُّوبَ بْنِ مُوسَى، عَنْ مَنْصُورِ بْنِ عَبْدِ الرَّحْمَنِ الْحَجَبِيِّ، عَنْ أُمِّهِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، - رضى الله عنها أَنَّهَا سُئِلَتْ عَنْ رَجُلٍ قَالَ مَالِي فِي رِتَاجِ الْكَعْبَةِ ‏.‏ فَقَالَتْ عَائِشَةُ يُكَفِّرُهُ مَا يُكَفِّرُ الْيَمِينَ ‏.‏ قَالَ مَالِكٌ فِي الَّذِي يَقُولُ مَالِي فِي سَبِيلِ اللَّهِ ثُمَّ يَحْنَثُ قَالَ يَجْعَلُ ثُلُثَ مَالِهِ فِي سَبِيلِ اللَّهِ وَذَلِكَ لِلَّذِي جَاءَ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي أَمْرِ أَبِي لُبَابَةَ ‏.‏

Yahya related to me from Malik from Ayyub ibn Musa from Mansuribn Abd ar-Rahman al-Hajabi from his mother that A'isha, umm al-muminin, may Allah be pleased with her, was asked about a man whodevoted his property to the door of Kaba. She said, "Let him dokaffara for it with the kaffara of the oath." Malik said,that someone who devoted all his property in the way of Allah, andthen broke his oath, should put a third of his property in the way ofAllah, as that was what the Messenger of Allah, may Allah bless himand grant him peace, did in the case of Abu Lubaba.
