One of the most beautiful this about the 
concept of worship in Islaam is the truly unique way in which it incorporates 
the feelings of love, fear and hope within the hearts of the worshippers of 
Allah. Understanding how to combine these three qualities into the worship 
('ibaadah) of Allah is one of the most essential things that every Muslim must 
grasp, ,not least because every sect which has drifted from the Straight Path 
has strayed in this aspect of worship. The deviation of the other Religions in 
this regards is clear for all to see: "God is Love! Jesus is Love!" 
say the Christians, denying the fact that God should be feared too. As for the 
Jews, then their hearts are filled only with hope - hope in the belief that the 
Fire will not touch them since they are the "Promised People".
In Islaam however, no worship is complete without the 
presence of all three qualities: LOVE of Allah, Hope in His Mercy and FEAR of 
His Punishment. Contemplate the opening Soorah of the Qur'aan - Sooratul 
Faatihah - and you will see for yourself.
Aaayah 1: "All Praise [and
    Thanks] are for Allah, Rabb of all the worlds."
In this opening aayah (verse) of the Qur'aan, we have 
LOVE of Allah and every time we recite this aayah we are testifying to our love 
for Allah. How is that you ask? IT is because in this aayah, we are 
acknowledging that Allah is our Rabb and the Rabb of all the worlds. Rabb is 
usually translated as 'the Lord', but this translation does not do justification 
to this name of Allah and all the meanings that this name carries. In reality 
Rabb means that Allah is the Creator of everything; He sustains and nourishes 
everything; He gives life and death; anything good which we have is from Him; 
everything is dependent on Him and nothing can happen unless He wills it. 
Furthermore, for the Muslim He - the Rabb - is the One who has guided us to the 
Truth and given us good morals and manners.
Thuis when we testify that Allah is out Rabb, then we 
are acknowledging that He is the One who has given us so many blessings - so 
many that is we tried to enumerate His blessings upon us, we could not count 
them. So how could we not love Him? After all, we know that when someone gives 
us even a small gift or shows even a small act of kindness towards us, then we 
develop so much love for them on account of that - so imagine then the love we 
should[1] have for our Rabb who has given us everything: nice families, shelter, 
security, food, health, and above all, Guidance to Islaam and the Sunnah. We 
should be overwhelming in our love for Him and thank Him and say: "All 
Praises [and Thanks] are for Allah, Rabbil-'aalameen."
Aayah 2: "The Rahman [Merciful] and 
the Raheem [Mercy-Giving]."
In the first aayah of Sooratul-Faatihah, Allah mentioned 
that He was ar-Rabb. In the next aayah two more of His beautiful names are 
mentioned: ar-Rahmaan and ar-Raheem. Ar-Rahman means that He is the Most 
Merciful, that is, His Nature or His Essence is Merciful. Ar-Raheem means that 
He is the Giver of Mercy, in other words, His actions are full of Mercy and He 
shows Mercy to His creation.[2]
When we mention these two names of Allah, then we have 
HOPE. Since He has described Himself as so full of Mercy then we have hope that 
He will forgive out sins, and no matter how numerous out sins may be, we should 
never lose this hope, because Allah has told us: "O My slaves who have 
transgressed against themselves! Despair not of the Mercy of Allah verily Allah 
forgives all sins [except shirk]. Truly He is the Oft-Forgiving, the 
Mercy-Giving." [az-Zumar (39):53].
The need to have FEAR in our worship is shown by the 
next aayah of Sooratul-Faatihah:
Aayah 3: "King/Master of the Day of 
Judegment."
When we recite this aayah we are reminding ourselves of 
the Day of Judgement - that awful Day, when we shall all stand before Allah, 
naked, uncircumcised and barefooted. Some will be sweating so much that it will 
go seventy arm-length into the earth. People will appear drunk though they are 
no. On this Day, every person will stand before Allah and account for his sins, 
knowing that not even the smallest action which he did is hidden from Allah:
"So whosoever does good equal to the 
weight of an atom shall see it. And whosoever does evil equal to the weight of 
an atom shall see it." [az-Zalzalah (99):7-8].
So when we recite this third aayah of Sooratul-Faatihah, 
we remind ourselves of this Judgement and accountability and that should bring 
about in us a sense of fear - that maybe out evil actions will be too great and 
we will be responsible for it - may Allah protect us from such a fate.
