SHAFAQNA (Shia International News Association) – The human’s heart cannot be a place for more than one main target of affection and whenever one thing attracts a person inherently, the love of that thing will capture the whole heart. Therefore the heart will target that thing and cannot have another target. Whilst remaining in the heart, that main target will attract all the affections. But the point here is about other affections which may exist along the main affection in the heart.
Imam Ali (AS) said: As the night and the day cannot add up together, the love of God and the world also cannot add up together . In another explanation, Imam Ali (AS) said: How could a person, who has the love of the world in his /her heart, claim to love God ? In Sermon Number 160, Imam Ali (AS) said: If the world appears great in the eyes of a person and if the position of the world inside a person appears to be magnificent and grand, certainly that person will prioritise the world to God .
