Sayyiduna Thawban (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Remain upright towards Quraysh as long as they remain upright towards you. When you do not do so, then place your swords on your shoulders and annihilate them (perhaps it means: annihilate those who oppose Quraysh). If you do not do so, then in that case you will become wretched farmers, eating from the labour of your own hands."
Al-Tabarani recorded it in al-Mu'jam al-Saghir and al-Mu'jam al-Awsat. The narrators of al-Mu'jam al-Saghir are thiqat (trustworthy). The hadith narrated by Sayyiduna al-Nu'man (may Allah be pleased with him) will come later.
