Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Accept the good from the Ansar who do good, and overlook the wrongdoer among them."
Imam al-Bazzar recorded this narration. Its chain contains Sadaqah bin Abdullah al-Samin, whom Duhaym and Abu Hatim declared thiqah (trustworthy) while a group declared him da'if (weak); the remaining narrators of this narration are thiqat (trustworthy).
