2. Ali ibn Ibrahim has narrated from Salmah ibn al-Khattab, from al-Hassan ibn Rashid from Ali ibn Isma’il al-Mithamiy from Habib al- Khath’amiy who has said the following: “Abu Ja‘far al-Mansur once wrote to Muhammad ibn Khalid, his governor of al-Madinah, to ask people of al-Madinah about the amount of zakat that was five for every two hundred and how it has become seven for every two hundred which was not as such in the time of the Messenger of Allah. He commanded him to include ‘Abd Allah ibn al-Hassan and Ja‘far ibn Muhammad, ‘Alayhi al-Salam, among the people asked. He (the narrator) has said, ‘He asked people of al-Madinah about it and they replied, “It is because people before us did so.’” He sent someone to ask ‘Abd Allah ibn al-Hassan about it. His answer was just like the answers of other people of al-Madinah. He then asked, ‘What do you say about it, O abu ‘Abd Allah?’ He (the Imam) replied, ‘The Messenger of Allah had levied one Awqiyyah on every forty. If you calculate, it becomes equal to seven. The weight was six and dirham was five Dawaniq each.’ He (the narrator) has said, ‘We calculate it and it was just as he (the Imam) had said.’ ‘Abd Allah ibn al-Hassan then came to the Imam and asked, ‘On the basis of what source have you come up with this calculation?’ He (the Imam) replied, ‘I read it in the book of your mother, Fatimah, ‘Alayha al-Salam .’ He (the narrator) has said, ‘He then returned. Muhammad ibn Khalid then sent his people to the Imam asking for the book of Fatimah, ‘Alayha al-Salam .’ Abu ‘Abd Allah, ‘Alayhi al-Salam, then sent the answer, ‘I only informed you about my reading it in the book of Fatimah, ‘Alayha al-Salam. I did not say that I have the book of Fatimah, ‘Alayha al-Salam, with me.’ Habib has said, ‘Muhammad ibn Khalid would say, “I have never seen anything like this.’””
IsnādAli ibn Ibrahim a rapporté de Salama ibn al-Khattab, de al-Hasan ibn Rashid, de Ali ibn Isma'il al-Mithami, de Habib al-Khath'ami, qui a dit : Abu Ja'far al-Mansur a écrit à Muhammad ibn Khalid, qui travaillait pour lui à Médine, pour interroger les gens de Médine sur les cinq (parties) de la zakat des deux cents (dirhams), comment cela s'est-il transformé en un poids de sept (dirhams), alors que cela n'était pas ainsi du temps du Messager d'Allah (que la paix et les bénédictions d'Allah soient sur lui). Il lui ordonna de questionner ceux qui interrogent Abdullah ibn al-Hasan et Ja'far ibn Muhammad (que la paix soit sur eux).
Il interrogea alors les habitants de Médine qui dirent : "Nous avons connu ceux qui étaient avant nous à ce sujet." Il envoya donc vers Abdullah ibn al-Hasan et Ja'far ibn Muhammad (que la paix soit sur eux) pour les interroger. Abdullah ibn al-Hasan répondit comme l'avaient dit les interrogés de Médine. Il lui demanda alors : "Que dis-tu, ô Aba Abdillah ?" Il répondit : "Le Messager d'Allah (que la paix et les bénédictions d'Allah soient sur lui) a fixé pour chaque quarantaine une quantité, et si tu calcules cela, cela correspond à un poids de sept (dirhams), alors que c'était auparavant un poids de six (dirhams), et les dirhams étaient de cinq dawaniq." Habib a dit : "Nous avons donc calculé cela et nous l'avons trouvé comme il l'avait dit." Abdullah ibn al-Hasan lui demanda alors : "D'où as-tu tiré cela ?" Il répondit : "Je l'ai lu dans le livre de ta mère Fatima." Puis il partit. Muhammad ibn Khalid lui envoya dire : "Envoie-moi le livre de Fatima (que la paix soit sur elle)." Abu Abdillah (que la paix soit sur lui) lui envoya dire : "Je t'ai seulement informé que je l'ai lu, mais je ne t'ai pas informé que je le possédais." Habib a dit : "Muhammad ibn Khalid me demanda alors : 'Je n'ai jamais vu quelque chose de tel auparavant.'"
