Ibn Jarir recorded that Yazid bin Abi Maryam said: “`Umar, may Allah be pleased with him, passed by Mu`adh bin Jabal and asked,
What is the foundation of this Ummah?
Three things, and they are the things that will bring salvation: Al-Ikhlas (doing a deed for Allah alone), which is the Fitrah with which Allah created mankind; Salah, which is the thing that tells a believer apart from a disbeliever; and obedience, which is protection.
You have spoken the truth.
