that the Messenger of Allah (ﷺ) said: "There is no one more truthful, that the sky has shaded and the earth has carried, than Abu Dharr."
Jami` at-Tirmidhi Book 49, Hadith 201
← Previous Hadith that the Messenger of Allah (ﷺ) said: "Rejoice, 'Ammar, the transgressing party shall kill you."

Jami` at-Tirmidhi Book 49, Hadith 200 Next Hadith → that the Messenger of Allah (ﷺ) said: "There is no one more truthful in speech, nor in fulfilling of promises, that sky has covered and the earth has carried, than Abu Dharr, the likeness of 'Eisa bin Mariam." So 'Umar bin Al-Khattab said, as if out of envy: "So do you acknowledge that for him, O Messenger of Allah?" He said: "Yes, so acknowledge it."
