Sayyiduna Qatadah bin Nu’man (may Allah be pleased with him) said something bad about the Quraysh, so the Messenger of Allah (peace and blessings be upon him) said: “Qatadah, restrain yourself regarding the Quraysh and do not insult them. Perhaps you will see that your deeds and actions are insignificant compared to those of a Qurayshi, and you will envy them when you see them. If it were not for the fear of the Quraysh’s arrogance, I would have told them what their status is with Allah.”
