HADITH OF THE DAY
CALL ADOPTED SONS BY
Narrated by Abdullah bin Umar
We used not to call Zaid bin Haritha the freed slave of Allah's Messenger (Peace & Blessings of Allah upon Him) except Zaid bin Muhammad till the Quranic Verse was revealed:
"Call them (adopted sons) by (the names of) their fathers; that is more than just in the Sight of Allah." (Quran-33:5)
