It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to me: "There is no one on the face of the earth, nor anyone under the shade of the sky, who is more truthful of tongue than Abu Dharr; he resembles Isa bin Maryam (peace be upon him)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ikrimah bin Ammar except al-Nadr bin Muhammad al-Jurashi."
