 Waqidi reports that Ibn Ubayy, at first, strove to bring about a reconciliation, and Tabari relates that Abd-Allah accused Muhammad of treachery and urged the Nadir to resist by promising aid.However, as the promised help failed to materialize, the Nadir surrendered and Muhammad expelled them from the city.Watt considered this to be the first instance in which Ibn Ubayy went beyond verbally criticizing Muhammad to intriguing against him, a practice Watt saw as continuing for the next two years.
