Is the meaning of the Hadith "None of you truly believes until he wishes for his brother what he wishes for himself" limited to loving good for one's Muslim brother in matters of the afterlife only, or does it include matters of both this world and the afterlife? And is a person's preference for himself in some worldly matters blameworthy and contradictory to the Hadith?

The meaning of the Hadith: "None of you believes until he loves for his brother what he loves for himself" is that a Muslim should love for his brother acts of obedience and permissible things, as narrated by Al-Nasa'i: "until he loves for his brother from goodness what he loves for himself." A Muslim's love for his brother's guidance and performance of obligatory duties is a wajib (obligatory act), while his love for his brother to acquire permissible worldly matters is mustahabb (recommended). What is required is for a Muslim to wish for his brother to find the equivalent of what he obtains for himself, not the exact same thing.
