You will not be a believer unless your love for Allah and His Messenger is above all other love, and that your desires, motivations and thoughts are according to the message. Think of those you love and obey in this world – your love and obedience to Allah must be above these, such that you even put your own desires aside for what Allah wants.
The early Muslims made monumental sacrifices for Islam, and one of the clearest examples is the emigration or Hijrah. The Muslims of Mekah (the Muhajireen) were commanded to emigrate to Madinah for protection from their persecutors and to forward the propagation of Islam. They were forced to abandon everything that they could not carry with them – their houses, crops, cattle, wells and date trees, including their potential income from these.
If you are rich, fear Allah and remember if you die with excess wealth, you have denied Allah's money its rightful place.
We should increase doing what Allah loves, and abstain from what Allah does not love. We should inculcate this as part of our conscious decision making process and use it as a tool for our own personal transformation.
Allah has also warned us against behaviour that He does not love. Naturally we should strive to avoid having these types of behaviour and characteristics.
