What is the ruling on those who say: We only worship Allah with love for him and we do not fear his punishment and we do not desire his reward?
This is a statement of the soofiyah; it is an error and refuge is sought with Allah. This is in opposition to the methodology of (all of) the Prophets (alayhimus Salaatu was Salaam).
Verily, they used to hasten on to do good deeds, and they used to call upon Us with hope and fear, and used to humble themselves before Us. [Surah Al-Anbiya’ Verse 90]
Those whom they call upon [like Isa (Jesus) – son of Maryam (Mary), Uzair (Ezra), angel] desire (for themselves) means of access to their Lord (Allah), as to which of them should be the nearest; and they [Isa (Jesus), Uzair (Ezra), angels and others] hope for His Mercy and fear His torment. Indeed the torment of your Lord is (something) to be afraid of. [Surah Al-Isra Verse 57]
Therefore, whoever worships Allah with fear only then he is a Khaarij; whoever worships Allah with hope only then he is from the murji’ah and whoever worships Allah with love only then he is a Soofi.
And (finally) whoever worships Allah with Love, Hope and Fear then he is a believer upon Tawheed.
