It is narrated from Sayyiduna Mu'awiyah bin Abi Sufyan (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Do not rush after something thinking that by hurrying towards it you will attain it, and do not hold back from something thinking that by holding back from it, it will be averted from you, if Allah has decreed it for you."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from the Messenger of Allah (peace and blessings be upon him) except Mu'awiyah (may Allah be pleased with him), and it is narrated from Mu'awiyah (may Allah be pleased with him) only with this chain, and Abd al-Wahhab is alone in narrating it."
