Muḥammad b. al-Ḥasan b. Aḥmad b. al-Walīd رضي الله عنه narrated to us, saying that al-Ḥusayn b. al-Ḥasan b. Abān narrated to him among others, from al-Ḥusayn b. Saʿīd, from Ibrāhīm b. Abī’l-Bilād, from his father, who raised it up to Amīr al-Muʾminīn عليه السلام. When the Imam was asked about a day (in the month of Ramaḍān) which is cast into doubt, he said: “I fast a day of Shaʿbān, liking that I extend it until I break the fast (at the end of) a day of the month of Ramaḍān.”
