Hadith 17:629
Ibn ‘Uyaynah narrated to us, from Sulayman al-Ahwal, who said: We were performing Tawaf and Maqsam was with us. Tawus began speaking to him and saying, "To us [come here]." We said, "Abu al-Qasim." He said, "By Allah, I will not use that kunya for him."
حدثنا بن عيينة عن سليمان الأحول قال كنا نطوف ومعنا مقسم فجعل طاوس يحدثه ويقول إلينا فقلنا أبو القاسم فقال والله لا أكنيه بها
