Abū Ṭalḥah the ophthalmologist to ask him for a specific prescription while he was on horseback, and I noticed that his beard was ash-grey.

Ibn Idrīs narrated, through Abū Isḥāq al-Shaybānī from ʿAbd al-Malik ibn Iyās al-Shaybānī, who said:
“I asked Ibrāhīm al-Nakhaʿī, ‘Whom shall we consult after you?’ He answered, ‘Ḥammād.’”

Ibn Idrīs added, “I never heard al-Shaybānī mention Ḥammād without commending him.”

Ibn ʿAwn said: “I saw Ḥammād enter upon Ibrāhīm carrying some atrāf (1), and he began asking Ibrāhīm about them. Ibrāhīm said to him, ‘What is this? Did I not forbid this?’ Ḥammād replied, ‘They are only atrāf.’”

Manṣūr narrated from Ibrāhīm that he said, “There is no harm in writing atrāf.”

Shurayk narrated from Jāmiʿ Abū Ṣakhrah who said: “I saw Ḥammād writing in the presence of Ibrāhīm, saying, ‘We seek no worldly gain by this,’ and he was wearing an Anbijānī cloak.”

Ibn ʿUyaynah said: “Maʿmar used to say, ‘Among these people I have not seen anyone more versed in jurisprudence than al-Zuhrī, Ḥammād, and Qatādah.’” He also said, “Ḥammād had a keener grasp of Ibrāhīm’s views than al-Ḥakam.”

Ibn Idrīs said: “I heard my father relate from Ibn Shubrumah, ‘No one has endowed me with knowledge more than Ḥammād.’”

Abū Bakr ibn ʿAyyāsh narrated from Mughīrah, who said: “We went to visit Ibrāhīm when he had withdrawn, and he said, ‘Turn to Ḥammād, for he has asked me about everything the people have asked me about.’”
