obligation of directing all hearts to Allah (Exalted be He) in all affairs and to devote worship to Him alone, because creatures are created for this reason (i.e. worship of Allah) and they are commanded to do so as previously stated in the Ayahs.
Worship Allâh and join none with Him (in worship)
The right of Allah over His slaves is that they should worship Him and not associate anything with Him.
Whoever dies while still invoking a rival (in worship) to Allah, will enter Hell (Fire).
And I (Allâh) created not the jinn and mankind except that they should worship Me (Alone).
are kinds of major Shirk because they are considered worship of other than Allah and requesting things from others, such as the dead and the absent, who are unable to do such things.
sent down the Book to you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) in truth: So worship Allâh (Alone) by doing religious deeds sincerely
Surely the religion (i.e. the worship and the obedience) is for Allâh only.
Allah (He may be Praised) explained that worship is for Him alone and His servants must devote worship to Him, because His command to the Prophet (peace be upon him) to devote worship to Him is a command for all people. The meaning of religion here is to worship, and worship means to obey Him as well as His Messenger (peace be upon him), and this includes supplication, seeking help, fear, hope, slaughter [of sacrificial animals], vow, Salah, Sawm (fasting) and other acts of worship commanded by Allah and His Messenger (peace be upon him).
And those who take Auliyâ' (protectors, helpers, lords, gods) besides Him (say): "We worship them only that they may bring us near to Allâh."
Verily, Allâh will judge between them concerning that wherein they differ. Truly, Allâh guides not him who is a liar, and a disbeliever.
Allah (He may be Praised) explains in this Ayah that disbelievers worship idols besides Him in the hope that they will draw them near to Him. This is the purpose of disbelievers both in the past and present. Allah (Exalted be He) refutes this claim, saying: Verily, Allâh will judge between them concerning that wherein they differ. Truly, Allâh guides not him who is a liar, and a disbeliever. Allah refutes their falsehood that their gods draw them near to Allah and exposes their Kufr (disbelief), because of worshiping others besides Him.
no one because He is Supreme over His servants and the Administrator of their affairs in the way He likes; unlike kings and leaders who are not able to do everything and do not know everything.
And if you ask them who created them, they will surely say: "Allâh."
Say (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ): "Who provides for you from the sky and the earth? Or who owns hearing and sight? And who brings out the living from the dead and brings out the dead from the living? And who disposes the affairs?" They will say: "Allâh." Say: "Will you not then be afraid of Allâh's punishment (for setting up rivals in worship with Allâh)?"
And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): "Worship Allâh (Alone), and avoid (or keep away from) Tâghût (all false deities i.e. do not worship Tâghût besides Allâh)."
Who is he that can intercede with Him except with His Permission
And there are many angels in the heavens, whose intercession will avail nothing except after Allâh has given leave for whom He wills and is pleased with.
and they cannot intercede except for him with whom He is pleased. And they stand in awe for fear of Him.
If you disbelieve, then verily, Allâh is not in need of you; He likes not disbelief for His slaves. And if you are grateful (by being believers), He is pleased therewith for you.
"O Messenger of Allah! Who is most deserving of your intercession?" The Messenger of Allah (peace be upon him) said: "It is he who says there is no deity but Allah sincerely from his heart," or said, "sincerely from his inner self."
For every prophet there is a granted supplication. Every prophet hastened in (making) his supplication, but I have reserved my supplication as intercession for my Ummah (nation) on the Day of Resurrection; and it will be attained, if Allah wills, by whoever from my Ummah dies, associating nothing with Allah.
Say: "To Allâh belongs all intercession."
So no intercession of intercessors will be of any use to them.
There will be no friend, nor an intercessor for the Zâlimûn (polytheists and wrongdoers), who could be given heed to.
And it is the disbelievers who are the Zâlimûn (wrongdoers).
And (remember) when Luqmân said to his son when he was advising him: "O my son! Join not in worship others with Allâh. Verily joining others in worship with Allâh is a great Zûlm (wrong) indeed.
