Does Allah's love for His servant and the servant's feeling of Allah's companionship cease due to the servant's sins, bearing in mind that every human sins and seeks forgiveness, and may commit sins unintentionally?

Allah has clarified to His servants that attaining His love and companionship is achieved by performing the obligatory duties and striving to draw near through supererogatory acts, as stated in the Hadith (definition) Qudsi: "My servant does not draw near to Me with anything more beloved to Me than what I have enjoined upon him, and My servant continues to draw near to Me with supererogatory acts until I love him." Sins and transgressions prevent the servant from reaching these high ranks. For the servant to find Allah's love and companionship once again, he must address his shortcomings in obedience and persistence in sin by adhering steadfastly to the Sacred Law.
