ʿUthmān ibn ʿAbd al-Ḥamīd al-Lāḥiqī narrated: “My father related to us, saying:
‘ʿUmar ibn ʿAbd al-ʿAzīz said, “I have never found anyone more knowledgeable than ʿUrwah ibn al-Zubayr, nor do I think that he knows anything of which I am ignorant.”’ (1)

Abū al-Zinād said, “The jurists of Madinah are four: Saʿīd, ʿUrwah, Qabīṣah, and ʿAbd al-Malik ibn Marwān.” (1)

Ibn al-Madīnī reported—from Sufyān, from al-Zuhrī—who said, “I saw ʿUrwah as an ocean that buckets cannot muddy.” (2)

Yaḥyā ibn Ayyūb transmitted—from Hishām—who said, “By Allah, we did not learn even one part out of two thousand parts—or one thousand parts—of my father’s hadith.” (3)

al-Aṣmaʿī related—from Mālik, from al-Zuhrī—who said:
“I asked Ibn Ṣuʿayr (4) about a matter of jurisprudence. He replied, ‘You should go to that man,’ and he pointed to Ibn al-Musayyab. I accompanied him for seven years, convinced there was no scholar besides him. Then I turned to ʿUrwah, and with him I made a spring gush forth from the midst of an ocean.” (5)

Ibn Abī al-Zinād narrated: ʿAbd al-Raḥmān ibn Ḥumayd ibn ʿAbd al-Raḥmān told me:
“I entered the mosque with my father and saw the people gathered around a man. My father said, ‘Look—who is that?’ I looked, and it was ʿUrwah. I informed him, astonished. He said, ‘My son, do not be surprised. I have seen the Companions of the Messenger of Allah, peace and blessings be upon him, asking him.’” (6)

Ibn ʿUyaynah reported—from al-Zuhrī—who said, “ʿUrwah used to win people’s hearts through his hadith.” (7)
