The Zanaadiqah - or the heretics - are groups, such as 
many of the Soofees who have become like the Christians and reduced the religion 
to just 'love' and so all their talk and all their mystical practices are 
centred around developing more 'love'.
It is thus clear how imbalances in any of the three 
qualities of worship can lead to major deviation and straying from the True 
Guidance, Therefore it is important for every Muslim to inculcate all three 
things in his heart properly. As was mentioned before, the fear and hope should 
be in equal proportions[6] but as for love, then that should be uppermost, As 
Fudayl ibn Iyyaad (d.187H) said: "The love is better than fear. The fear 
checks us from sinning, and the love makes us to do what is prescribed with an 
open heart."[7]
May Allah Subhaanahu wa Ta'aala grant us what we hope 
for and protect us from what we fear. Aameen.

1 This is why the Prophet, sallallaahu 'alaihi wa sallam 
encouraged us to give gifts to one another. He said: "Give gifts to one 
another, you will come to love one another." [Hasan - Collected in 
al-Bukhaaree's al-Adabul-Mufrad & declared hasan by al-Albaanee in 
al-Irwaa(1601).

Badaa'i-ul-Faawaa'id & others.

6 This was the opinion of most of the Salaf. Al-Fudayl 
ibn 'Iyyaad said that when one is healthy and well, then fear should 
predominate, but when terminally ill then hope should predominate - so that one 
should strive to do good when well and not despair of Allah's Mercy when 
terminally ill. [At-Takhweef minan-Naar].

that some scholars hold that fear is better than love. Allah knows best.
