وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عُثْمَانَ بْنِ حَفْصِ بْنِ عُمَرَ بْنِ خَلْدَةَ، عَنِ ابْنِ شِهَابٍ، أَنَّهُ بَلَغَهُ أَنَّ أَبَا لُبَابَةَ بْنَ عَبْدِ الْمُنْذِرِ، حِينَ تَابَ اللَّهُ عَلَيْهِ قَالَ يَا رَسُولَ اللَّهِ أَهْجُرُ دَارَ قَوْمِي الَّتِي أَصَبْتُ فِيهَا الذَّنْبَ وَأُجَاوِرُكَ وَأَنْخَلِعُ مِنْ مَالِي صَدَقَةً إِلَى اللَّهِ وَإِلَى رَسُولِهِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ يُجْزِيكَ مِنْ ذَلِكَ الثُّلُثُ ‏"‏ ‏.‏

"The Messenger of Allah, may Allah bless him and grant himpeace, said, "Giving away a third of it is enough for you." Translation Not Available
