Arabic hadith text
حَدَّثَنَا هِشَامُ بْنُ عَبْدِ الْمَلِكِ الْحِمْصِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ حَرْبٍ، حَدَّثَتْنِي أُمِّي، عَنْ أُمِّهَا، أَنَّهَا سَمِعَتِ الْمِقْدَامَ بْنَ مَعْدِيكَرِبَ، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ " مَا مَلأَ آدَمِيٌّ وِعَاءً شَرًّا مِنْ بَطْنٍ حَسْبُ الآدَمِيِّ لُقَيْمَاتٌ يُقِمْنَ صُلْبَهُ فَإِنْ غَلَبَتِ الآدَمِيَّ نَفْسُهُ فَثُلُثٌ لِلطَّعَامِ وَثُلُثٌ لِلشَّرَابِ وَثُلُثٌ لِلنَّفَسِ "
