Narrated Ziyad ibn al-Harith as-Suda'i:

I came to the Messenger of Allah ﷺ and swore allegiance to him, and after telling a long story he said: Then a man came to him and said: Give me some of the sadaqah (alms). The Messenger of Allah ﷺ said: Allah is not pleased with a Prophet's or anyone else's decision about sadaqat till He has given a decision about them Himself. He has divided those entitled to them into eight categories, so if you come within those categories, I shall give you what you desire.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، حَدَّثَنَا عَبْدُ اللَّهِ، - يَعْنِي ابْنَ عُمَرَ بْنِ غَانِمٍ - عَنْ عَبْدِ الرَّحْمَنِ بْنِ زِيَادٍ، أَنَّهُ سَمِعَ زِيَادَ بْنَ نُعَيْمٍ الْحَضْرَمِيَّ، أَنَّهُ سَمِعَ زِيَادَ بْنَ الْحَارِثِ الصُّدَائِيَّ، قَالَ أَتَيْتُ رَسُولَ اللَّهِ ﷺ فَبَايَعْتُهُ فَذَكَرَ حَدِيثًا طَوِيلاً قَالَ فَأَتَاهُ رَجُلٌ فَقَالَ أَعْطِنِي مِنَ الصَّدَقَةِ . فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ
" إِنَّ اللَّهَ تَعَالَى لَمْ يَرْضَ بِحُكْمِ نَبِيٍّ وَلاَ غَيْرِهِ فِي الصَّدَقَاتِ حَتَّى حَكَمَ فِيهَا هُوَ فَجَزَّأَهَا ثَمَانِيَةَ أَجْزَاءٍ فَإِنْ كُنْتَ مِنْ تِلْكَ الأَجْزَاءِ أَعْطَيْتُكَ حَقَّكَ " .
