It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: On the Day of Resurrection, Allah Almighty will say: Remove from Hell every person who used to declare "There is no god but Allah" and in whose heart there is goodness equal to a grain of barley. Then Allah Almighty will say: Remove from Hell every person who used to declare "There is no god but Allah" and in whose heart there is goodness equal to a grain of wheat. Then Allah Almighty will say: Remove from Hell every person who used to declare "There is no god but Allah" and in whose heart there is goodness equal to the weight of a particle.
