And he sallallaahu ‘alayhi wa sallam said:
“When the son of Aadam wakes up in the morning, then all of the body-parts humble themselves to the tongue, saying: Fear Allaah with regards to us, for we are dependant upon you. If you have istiqaamah, then we have istiqaamah, and if you swerve, then we also swerve.”
