Worship ‎(العبادة)

Its definition: It is a comprehensive term for all that Allah loves and is pleased with from sayings and deeds, both outer and inner.

Allah commanded many kinds of worship, such as Islam, Eemaan and Ihsaan, which includes: Supplication (Du’aa), Fear (Khawf), Hope (Rajaa), Reliance (Tawakkul), Longing (Raghbah) and Dreading (Rahbah), Submissiveness (Khushoo’), Awe (Khashyah), Repentance (Inaabah), Seeking Assistance (Isti’aanah), Seeking Refuge (Isti’aadhah), Asking for Help (Istighaathah), Offering Sacrifices (Dhabah), Making Oaths (Nadhar) and all of the other types of worship that Allah commanded – all of these belong to Allah, alone. The proof for this is Allaah’s saying: [72:18]

And Allah says: [98:05]

And they were commanded not, but that they should worship Allah, and worship none but Him Alone (abstaining from ascribing partners to Him).

So whoever directs any part of these (acts of worship) to other than Allah, then he has committed major Shirk, is a polytheist, disbeliever and his recompense is an eternal life in the Hellfire. 

The proof for this is Allah’s saying: [72:20]

And Allah says: [23:117]

And Allah says: [5:72]

It is stated in a hadeeth: “The supplication is the core of worship.” 

The proof for this (i.e. supplication) is Allah’s saying: [40:60]

The proof for Fear (khawf) is Allah’s saying: [3:175]

so fear them not, but fear Me, if you are (true) believers.

The proof for Hope (Rajaa) is Allah’s saying: [18:110] 

So whoever hopes for the meeting with their Lord, let them do good deeds and associate none in the worship of their Lord.

The proof for Reliance (Tawakkul) is Allah’s saying: [5:23]

And put your trust in Allah if you are believers indeed. 

And His saying: [65:3]

And whosoever puts his trust in Allah, then He will suffice him.

The proof for Longing (Raghbah) and Dreading (Rahbah) and Submissiveness (Khusoo’) is Allah’s saying: [21:90] 

Verily, they used to rush to do good deeds, and they would call on Us, longing (His reward) and dreading (His punishment), and they used to humble themselves submissively before Us. 

The proof for Awe (Khashyah) is Allah’s saying: [2:150] 

So do not be in awe of them, but have awe of Me.

The proof for Repentance (Inaabah) is Allah’s saying: [39:54]

And turn in repentance and in obedience with true Faith (Islamic Monotheism) to your Lord and submit to Him (in Islam)   

The proof for Seeking Assistance (Isti’aanah) is Allah’s saying: [1:5] 

You alone do we worship and in You alone do we seek assistance (in each and everything).

And in the hadeeth: “When you ask for assistance then seek assistance in 

Allah.” 

The proof for Seeking Refuge (Isti’aadhah) is Allah’s saying: [113:1] and [114:1]

The proof for Asking for Help (Istighaathah) is Allah’s saying: [8:9]

(Remember) when you sought help of your Lord and He answered you...

The proof for offering sacrifices (Dhabah) is Allah’s saying: [6:162-163]

And from the Sunnah is: “May Allah curse the one who offers a sacrifice to other 

than Allah.” 

The proof for Making Oaths (Nadhar) is Allah’s saying: [76:7]
