3. Sahl ibn Ziyad has narrated from ‘Abd al-Rahman ibn Salim from his father who has said the following: “I once asked abu ‘Abd Allah , ‘Are there for Muslims other ‘Id besides, Friday, the tenth of the month of Dhul Hajjah and the first day of the month of Shawwal?’ He (the Imam) replied, ‘Yes, there is such a day, in fact, it is of greater importance.’ I then asked, ‘I pray to Allah to keep my soul in service for your cause, which days are they?’ He replied, ‘One is the day during which the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, announced the appointment of ’Amir al-Mu’minin (as the executor of his will), saying, “Whoever’ s guardian I am, Ali also is his guardian.’” I then asked, ‘Which day is this day?’ He replied, ‘What do you have to do with the day; the year goes around, however, it is the eighteenth of the month of Dhul Hajjah.’ I then asked, ‘What should we do during this day?’ He replied, ‘You should pay attention to Allah, majestic is whose mention, by fasting, worshipping and speaking of Muhammad and his family, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause. The Messenger of Allah advised ’Amir al-Mu’minin to celebrate this day as ‘Id. This is what the prophets would do. They would advise the executors (of their wills) to celebrate this day as a day of ’Id.’”
