Sahih Muslim Book - 32, Hadith - 4578

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ وَمُحَمَّدُ بْنُ رَافِعٍ وَعَبْدُ بْنُ حُمَيْدٍ - قَالَ ابْنُ رَافِعٍ حَدَّثَنَا وَقَالَ الآخَرَانِ أَخْبَرَنَا عَبْدُ الرَّزَّاقِ - أَخْبَرَنَا مَعْمَرٌ عَنِ الزُّهْرِىِّ عَنْ مَالِكِ بْنِ أَوْسِ بْنِ الْحَدَثَانِ قَالَ أَرْسَلَ إِلَىَّ عُمَرُ بْنُ الْخَطَّابِ فَقَالَ إِنَّهُ قَدْ حَضَرَ أَهْلُ أَبْيَاتٍ مِنْ قَوْمِكَ. بِنَحْوِ حَدِيثِ مَالِكٍ. غَيْرَ أَنَّ فِيهِ فَكَانَ يُنْفِقُ عَلَى أَهْلِهِ مِنْهُ سَنَةً وَرُبَّمَا قَالَ مَعْمَرٌ يَحْبِسُ قُوتَ أَهْلِهِ مِنْهُ سَنَةً ثُمَّ يَجْعَلُ مَا بَقِىَ مِنْهُ مَجْعَلَ مَالِ اللَّهِ عَزَّ وَجَلَّ.

It was narrated that Malik bin Aws bin Al-Hadathan said: 'Umar bin Al-Khattab sent for me and said: some families of your people have come to me... a Hadith like that of Malik (no. 4578), except that it says ('Umar bin Al-Khattab said): He (s.a.w) used to spend his annual expenditure on his family from it. And Ma'mar said: he would keep his family's annual sustenance from it, then whatever was left he would spend in the cause of Allah.
