Translation
Narrated Abu Qilabah on the authority of Anas (RA)

Allah's Messenger (ﷺ) said: "The most versed in the rules of inheritance among you is Zaid bin Thabit."[Reported by Ahmad and al-Arba'a except Abu Dawud. at-Tirmidhi, Ibn Hibban and al-Hakim graded it Sahih (authentic). However, it was considered defective due to being Mursal (missing link in the chain after the Tabi'i)].
