In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Abdur-Rahmaan bin Abee Layla (rahimahullaah) said: I have met a hundred and twenty companions of the Messenger (sallal-laahu-alayhi-wasallam) in this Masjid and not a single one of them would be asked about a hadeeth, except he wished that his brother would suffice him in (answering). Then the affair came under the commission of a people, who claimed knowledge at present,–they give answers in affairs which if presented to Umar Ibnul Khattaab (radiyallaahu-anhu), he would have gathered the (Sahaabah of) Badr to consult them.
