حدثنا أبي - رحمه الله - قال: حدثنا سعد بن عبد الله، قال: حدثنا محمد بن عيسى بن عبيد، عن عبيد الله بن عبد الله الدهقان، عن درست بن أبي منصور الواسطي، عن إبراهيم بن عبد الحميد، عن أبي الحسن عليه السلام قال: دخل رسول الله صلى الله عليه وآله المسجد فإذا جماعة قد أطافوا برجل فقال: ما هذا؟ فقالوا: علامة يا رسول الله. فقال: وما العلامة؟ قالوا: أعلم الناس بأنساب العرب ووقائعها وأيام الجاهلية وبالاشعار، فقال صلى الله عليه وآله: ذاك علم لا يضر من جهله ولا ينفع من علمه.
1. We were told by my father, may Allah grant him mercy, that he said: We were told by Sa’d bin Abdullah, that he said: We were told by Muhammed bin Isa bin Ubaid, from Ubaidullah bin Abdullah al-Dahqan, from Darast bin Abi Mansur al-Wasiti, from Ibrahim bin Abdul-Hamid, from Abu’l-Hasan, peace be upon him, that he said: The Messenger of Allah, Allah’s blessings be upon him and his Family, entered the Mosque, and a group of people were circling around a man, so he said: What is this? They said: A great scholar, O Allah’s Messenger. Then he said: And what great scholar (is he)? They said: The most knowledgeable among the people about the lineages of the Arabs, their incidents, the days of the Jahiliya and poetry. Then he, Allah’s blessings be upon him and his Family, said: That is a knowledge that does not harm the one who is ignorant of it, nor does it benefit the one who knows it.
