It is narrated from Sayyiduna Abu Sa'id (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) offered the funeral prayer for al-Najashi.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Fitr except Abdullah bin Abd al-Quddus; Abbad bin Ya'qub is alone in it."
