Jami` at-Tirmidhi 2593

From Anas, that the Messenger of Allah (s.a.w) said – Hisham (one of the narrators) narrated it:“Some will exit the Fire,” Shu`bah (another narrator) narrated it: 'Remove from the Fire whoever said La ilaha illallah and had good in his heart equal to the weight of a grain of barley. Remove from the Fire anyone who said La Ilaha illallah and had good in his heart equal to the weight of a grain of wheat. Remove from the Fire anyone who said La ilaha illallah and had good in his heart equal to the weight of a speck.” And Shubah said: “What is equal to the weight of a light piece of corn.” (Sahih) Other chains report similar narrations
