رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ عَبْدِ اَللَّهِ بْنِ سِنَانٍ قَالَ قَالَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: «أُنْزِلَتْ إِلَيْهِ آيَةُ اَلزَّكَاةِ « خُذْ مِنْ أَمْوٰالِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَ تُزَكِّيهِمْ بِهٰا » فِي شَهْرِ رَمَضَانَ فَأَمَرَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ مُنَادِيَهُ فَنَادَى فِي اَلنَّاسِ «أَنَّ اَللَّهَ تَبَارَكَ وَ تَعَالَى قَدْ فَرَضَ عَلَيْكُمُ اَلزَّكَاةَ كَمَا فَرَضَ عَلَيْكُمُ اَلصَّلاَةَ فَفَرَضَ اَللَّهُ عَلَيْكُمْ مِنَ اَلذَّهَبِ وَ اَلْفِضَّةِ وَ اَلْإِبِلِ وَ اَلْبَقَرِ وَ اَلْغَنَمِ وَ مِنَ اَلْحِنْطَةِ وَ اَلشَّعِيرِ وَ اَلتَّمْرِ وَ اَلزَّبِيبِ» وَ نَادَى فِيهِمْ بِذَلِكَ فِي شَهْرِ رَمَضَانَ وَ عَفَا لَهُمْ عَمَّا سِوَى ذَلِكَ » قَالَ «ثُمَّ لَمْ يَتَعَرَّضْ لِشَيْءٍ مِنْ أَمْوَالِهِمْ حَتَّى حَالَ عَلَيْهِمُ اَلْحَوْلُ مِنْ قَابِلٍ فَصَامُوا وَ أَفْطَرُوا فَأَمَرَ عَلَيْهِ اَلسَّلاَمُ مُنَادِيَهُ فَنَادَى فِي اَلْمُسْلِمِينَ «أَيُّهَا اَلْمُسْلِمُونَ زَكُّوا أَمْوَالَكُمْ تُقْبَلْ صَلاَتُكُمْ» » قَالَ «ثُمَّ وَجَّهَ عُمَّالَ اَلصَّدَقَةِ وَ عُمَّالَ اَلطَّسُوقِ ».
Al-Hasan ibn Mahbub reported from Abdullah ibn Sinan, who said: Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq (a.s) said: "The verse of Zakat was revealed: 'Take alms from their wealth to purify them and cleanse them with it' (Surah At-Tawbah 9:103), in the Month of Ramadan. The Messenger of Allah (swt), peace and blessings be upon him and his family, ordered his announcer to proclaim to the people: 'Allah (swt), Blessed and Exalted, has made Zakat obligatory upon you as He has made prayer obligatory upon you. Allah (swt) has prescribed Zakat for gold, silver, camels, cows, sheep, wheat, barley, dates, and raisins.' He announced this during the Month of Ramadan and exempted them from everything else." The Imam continued: "Then he did not take anything from their wealth until a full year had passed. When the following year came, they fasted and broke their fast. Then the Messenger of Allah (swt), peace and blessings be upon him, ordered his announcer to call out among the Muslims: 'O Muslims, pay the Zakat of your wealth so that your prayers may be accepted.' He then sent out collectors for Zakat and tax collectors."
