Muḥammad b. Ibrāhīm b. Isḥāq narrated to us, saying that ʿAbd al-ʿAzīz b. Yaḥyā narrated to him among others, saying that Muḥammad b. Zakariyyā narrated to him among others, saying that Aḥmad b. Abī ʿAbd Allāh al-Kūfī narrated to him among others, from Sulaymān al-Marwazī, from al-Riḍā, ʿAlī b. Mūsā عليه السلام, that he said: “Whoever fasts in the month of Ramaḍān, establishing faith in and having accounted for its reward, will have forgiven whatever preceded of his sins and whatever comes after of them. The pen will not run upon the fasting person until he breaks his fast, as long as he does not do anything to invalidate his fast. The pen will not run upon the pilgrim until he returns to his home, as long as he does not do anything to invalidate his pilgrimage. The pen will not run upon the sleeping person until he wakes up, as long as he does not do anything prohibited in his sleep. The pen will not run upon the youth until he reaches biological maturity. The pen will not run upon he who struggles in the way of Allāh until he turns back to his home, as long as he does not do anything to invalidate his struggling. Nor will the pen run upon the maniac until he regains sanity, nor will the pen run upon the convalescent individual until he recovers his health.” Then he عليه السلام said: “Verily, the merchandise of Allāh is affordable, so purchase it before it becomes expensive!”
