Ali ibn Hatim, from Muhammad ibn Ja’far ibn Ahmad ibn Buttah al-Qummi, from Muhammad ibn al-Husayn ibn Abi al-Khattab, from Muhammad ibn Sinan. And Abu Muhammad Harun ibn Musa said: Muhammad ibn Ali ibn Mamar narrated to us, from Muhammad ibn al-Husayn ibn Abi al-Khattab, from Muhammad ibn Sinan, from al-Mufaddal ibn Umar, from Abu Abdillah (a.s), peace be upon him, that he said: Imam al-Sadiq (a.s) said: “In the Month of Ramadan, there is an additional (supererogatory) one thousand rak’ahs prayed.” He (Mufaddal) said: “I asked, ‘And who is able to do that?’” Imam (a.s) said: “It is not as you think. Do you not pray in the Month of Ramadan an additional one thousand rak’ahs (within the) nineteen nights of it? (Do you not read) twenty rak’ahs each night; and on the night of the nineteenth, one hundred rak’ahs; and on the night of the twenty-first, one hundred rak’ahs; and on the night of the twenty-third, one hundred rak’ahs; and you pray on eight nights of the last ten nights thirty rak’ahs each night? That is nine hundred and twenty rak’ahs.” He (Mufaddal) said: “I asked, ‘May Allah (swt) make me your ransom! You have relieved me the matter had weighed heavily upon me, but when you brought me the explanation, you relieved me. So how is the one thousand rak’ahs completed?’” Imam (a.s) said: “You pray on every Friday of the Month of Ramadan four rak’ahs for the Commander of the Faithful (a.s), peace be upon him, and you pray two rak’ahs for the daughter of Muhammad (saws), may Allah (swt) bless him and his family, and after the two rak’ahs you pray four rak’ahs for Ja’far al-Tayyar (a.s). And you pray on the eve of Friday during the last ten nights twenty rak’ahs for the Commander of the Faithful (a.s), peace be upon him, and you pray on the evening of Friday, which is the night of Saturday, twenty rak’ahs for the daughter of Muhammad (saws), may Allah (swt) bless him and his family.” Then Imam (a.s) said: “Listen, retain, and teach your trustworthy brothers these four rak’ahs and the two rak’ahs, for they are the best of prayers after the obligatory ones. Whoever prays them during the Month of Ramadan or outside of it, departs (from prayer) while there remains no sin between him and Allah (swt), the Majestic.” Then Imam (a.s) said: “O Mufaddal ibn Umar, in all of these prayers I mean the supererogatory prayers of the Month of Ramadan, you recite ‘al-Hamd’ (Surah al-Fatihah) and ‘Qul huwa Allahu Ahad’ (Surah Ikhlas) in them all. If you wish, recite Surah Ikhlas once, or if you wish, three times, or five, or seven, or even ten times. As for the prayer of the Commander of the Faithful (a.s), in each rak’ah, you recite ‘al-Hamd’ (Surah al-Fatihah) and fifty times ‘Qul huwa Allahu Ahad’ (Surah Ikhlas). And in the prayer of the daughter of Muhammad (saws), peace be upon her, in the first rak’ah you recite ‘al-Hamd’ (Surah al-Fatihah) and ‘Inna anzalnahu fi laylati al-qadr’ one hundred times; and in the second rak’ah, you recite ‘al-Hamd’ (Surah al-Fatihah) and ‘Qul huwa Allahu Ahad’ (Surah Ikhlas) one hundred times. Then, when you finish with the salam after the two rak’ahs, recite the Tasbih of (Sayyida) Fatimah al-Zahra (s.a), peace be upon her, which is: ‘Allahu Akbar’ thirty-four times, ‘al-Hamdu lillah’ thirty-three times, and ‘SubhanAllah’ thirty-three times. By Allah (swt), if there were anything better than it, the Messenger of Allah (swt), may Allah (swt) bless him and his family, would have taught it to her.” And Imam (a.s) said to me: “In the prayer of Ja’far (al-Tayyar (a.s)) , you recite in the first rak’ah ‘al-Hamd’ (Surah al-Fatihah) and ‘Idha zulzilati’ (Surah Az-Zalzalah); and in the second, ‘al-Hamd’ (Surah al-Fatihah) and ‘al-Adiyat’; and in the third, ‘al-Hamd’ (Surah al-Fatihah) and ‘Idha jaa’nasrullah’ (Surah An-Nasr); and in the fourth, ‘al-Hamd’ (Surah al-Fatihah) and ‘Qul huwa Allahu Ahad’ (Surah Ikhlas).” Then Imam (a.s) said to me: “O Mufaddal, (Allah (swt) says) ‘That is the bounty of Allah (swt), He (azj) gives it to whom He (azj) wills, and Allah (swt) is the Possessor of great bounty.’ (Surah Al-Jumuʿah 62:4)”
