Hadith 2123

حَدَّثَنَا مُحَمَّدُ بْنُ مَخْلَدٍ ، ثنا عُثْمَانُ بْنُ صَالِحٍ الْخَيَّاطُ ، ثنا بِشْرُ بْنُ عُمَرَ ، قَالَ : قُلْتُ لِمَالِكِ بْنِ أَنَسٍ : أَعْطِنِي مُدَّ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَدَعَا بِهِ ، فَجَاءَ بِهِ الْغُلامُ ، فَأَعْطَانِيهِ فَأَرَيْتُهُ مَالِكًا ، فَقُلْتُ : هَذَا هُوَ ؟ قَالَ : " نَعَمْ ، هُوَ مُدُّ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ " ، ثُمَّ قَالَ : " لَمْ أُدْرِكِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، وَهَذَا الَّذِي يَتَحَرَّى بِهِ مُدُّ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ " ، قُلْتُ : بِهَذَا تُعْطَى زَكَاةُ الْعُشُورِ وَالصَّدَقَاتُ وَالْكَفَّارَاتُ ؟ قَالَ : " نَعَمْ ، نَحْنُ نُعْطِي بِهِ " ، قُلْتُ : فَأَرَادَ رَجُلٌ أَنْ يُعْطِيَ زَكَاةَ رَمَضَانَ وَكَفَّارَةَ الْيَمِينِ بِمُدٍّ هُوَ أَكْبَرُ مِنْ هَذَا ، قَالَ : " لا ، وَلَكِنْ لِيُعْطِ بِهَذَا الْمُدِّ ، ثُمَّ لِيَزِدْ بَعْدُ مَا شَاءَ " .
Bishr bin Umar narrates: I requested Imam Malik to grant me the *Mudd* (a specific measure) of the Prophet Muhammad (peace be upon him). Imam Malik had it brought, a servant brought it and gave it to him. I showed it to Imam Malik and asked: Is this the one? He replied: Yes! This is the *Mudd* of the Prophet Muhammad (peace be upon him). Then he said: This is not the very specific measure that the Prophet Muhammad (peace be upon him) himself used, but rather it is a measure according to its measurement. (The narrator says) I asked: Do you people pay your zakat, charity, expiations, etc., according to this? He replied: Yes! We make payments according to this. I said: If a person wants to give Sadaqat al-Fitr or expiation for an oath according to the *Mudd* (which is larger than this), will it be valid? He said: No! He should pay according to this *Mudd*, and after that, he may give as much more as he wishes.
