The Source of Traditions on Imam al-Riḍā (Vol 1) · Hadith 133 (#Ḥadīth #25)

25 - وَبِهذَا الإسناد عَنْ مُحَمَّدِ بْنِ سَنان قالَ سَأَلْته - يَعْنِي الرِّضا a.sُ - عَنِ الاسم ما هُوَ؟ فَقالَ: صِفَةٌ لِمَوصُوف.

11-25 According to the same documentation, it is narrated that Muhammad ibn Sinan asked him (s) (i.e. Al-Ridha (s)) what a name is. The Imam (s) replied, “It is something to describe something else with.”
