Tahdhīb al-Aḥkām|Volume 4|Book 1|Chapter 25
اِبْنُ قُولَوَيْهِ عَنْ جَعْفَرِ بْنِ مُحَمَّدِ بْنِ مَسْعُودٍ عَنْ جَعْفَرِ بْنِ مَعْرُوفٍ قَالَ: كَتَبْتُ إِلَى أَبِي بَكْرٍ اَلرَّازِيِّ فِي زَكَاةِ اَلْفِطْرَةِ وَسَأَلْنَاهُ أَنْ يَكْتُبَ فِي ذَلِكَ إِلَى مَوْلاَنَا يَعْنِي عَلِيَّ بْنَ مُحَمَّدٍ عَلَيْهِ اَلسَّلاَمُ فَكَتَبَ أَنَّ ذَلِكَ قَدْ خَرَجَ لِعَلِيِّ بْنِ مَهْزِيَارَ »أَنَّهُ يُخْرَجُ مِنْ كُلِّ شَيْءٍ اَلتَّمْرِ وَ اَلْبُرِّ وَ غَيْرِهِ صَاعٌ« وَ لَيْسَ عِنْدَنَا بَعْدَ جَوَابِهِ عَلَيْنَا فِي ذَلِكَ اِخْتِلاَفٌ.
Ibn Qulawayh, from Jafar ibn Muhammad ibn Masud, from Jafar ibn Maruf, who said:
I (narrator) wrote to Abu Bakr al-Radhi regarding ‘Zakat al-Fitrah’, and we asked him to write concerning that to our master, meaning Imam Ali ibn Muhammad عليه السلام, peace be upon him. So al-Radhi wrote that this had already come out to Ali ibn Mahziyar: “That one sa’ is to be taken out from everything: dates, wheat (burr), and other than it.” And after his answer to us regarding that, there is no disagreement among us.
