A man of the Banu Kinaanah tribe narrates, “I saw Rasulullah (sallallahu ‘alaihi wasallam) in the market of Zul Majaaz proclaiming, ‘O people! Say Laa ilaaha illallaah, you will be successful.’
“At the same time, Abu Jahal was throwing sand at Rasulullah (sallallahu ‘alaihi wasallam) saying, ‘O people! Do not be deceived by this man! He wishes to separate you from Laat and ‘Uzzaa!’
“However, Rasulullah (sallallahu ‘alaihi wasallam) calmly continued with his efforts without even a glance at Abu Jahal.”
