محمد بن يحيى، عن أحمد بن محمد، عن بعض أصحابه، عن إبراهيم بن أبي البلاد قال: أخذني العباس بن موسى فأمر فوجئ فمي (١) فتزعزعت أسناني فلا أقدر أن أمضغ الطعام فرأيت أبي في المنام ومعه شيخ لا أعرفه فقال أبي رحمه الله: سلم عليه فقلت: يا أبه من هو؟ فقال: هذا أبو شيبة الخراساني (٢) قال: فسلمت عليه فقال: مالي أراك هكذا؟ قال:قلت: إن الفاسق العباس بن موسى أمرني فوجئ فمي فتزعزعت أسناني: فقال لي شدها بالسعد، فأصبحت فتمضمضت بالسعد فسكنت أسناني.
5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from certain persons of his people from Ibrahim ibn Ibrahim ibn abu al-Balad who have said the following: “Al-‘ Abbas ibn Musa took me and commanded to hit my mouth, so my teeth became shaky and I could not chew food. I then saw my father in my dream. There was an old man with him whom I could not recognize. My father, may Allah grant him mercy, said to me to offer greeting of peace to him.’ I then asked, ‘Father, who is he?’ He replied, ‘He is abu Shaybah al-Khurasaniy (of companions of abu Ja‘far ).’ I offered him greeting of peace and he asked, ‘Why do I see you in this condition?’ I replied, ‘Sinful al-‘Abbas ibn Musa commanded to hit on my mouth and my teeth have become shaky.’ He said, ‘Tie them down with cyperus.’ In the morning I rinsed my teeth with al-Sa‘d and my teeth calmed down.’”
