Abdul Rahman bin Abi Layia, from his father, from the MESSENGER OF ALLAH (SWT) who said:
No slave of ALLAH (SWT) is considered to be a believer unless he loves me more than he loves himself, loves my family more than he loves his own family, loves my progeny more than he loves his own progeny, and loves my identical counterpart (the Commander of the Believers(ASWS)) more than he loves himself.
(Ref: Amaali of Sadouq 274, Elal Al-Sharae 140)
