IBNHIBBAN 4428:
from Ubay b. Kaʿb —
Sūrat al-Aḥzāb was equivalent ˹in size˺ to Sūrat al-Baqarah and there was ˹an Āyah˺ in it: "al-shaykhu wa-al-shaykhah idhā zanayā fārjumūhumā al-battata (The ˹married˺ man and a woman, if they commit adultery, then absolutely stone them.)"
ابن حبّان ٤٤٢٨:
عن ابي بن كعب —
كَانَتْ سُورَةُ الْأَحْزَابِ تُوَازِي سُورَةَ الْبَقَرَةِ فَكَانَ فِيهَا {الشَّيْخُ وَالشَّيْخَةُ إِذَا زَنَيَا فَارْجُمُوهُمَا الْبَتَّةَ}
