The most evident witness of this calling...
The most evident witness of this calling, is because it is accompanied with the belief in their divinity and lordship, as in the following verse, it states clearly that: "so their God's whom they called upon besides Allah did not avail them." Therefore, the previously discussed verses are not relevant to our subject, which is the request of a slave from another without considering him as God or the Lord who has the full choice and possession in the affairs related to this world and the hereafter.
However, he is considered as a beloved slave of Allah who was chosen by Him, and given the leadership and imamate and the position of messengership; and such are the persons who have been promised that their prayers for the servants of God shall be accepted.
The Holy Quran recounts as this stage that: " and had they, when they were unjust to themselves, come to you and asked for forgiveness of Allah and the Apostle had (also) asked forgiveness for them, they would have found Allah to be oft-returning (to mercy), Merciful." Thirdly, the previously mentioned verses are a clear evidence of what is meant by 'calling' i.e., not all kinds of requesting and seeking of needs.
Calling can be considered as worship as in the following verse, but it should be noted that immediately after mentioning the word, 'calling', the similar meaning is mentioned in the phrase, 'worship' "And your Lord says: call upon me, I will answer you; surely, those who are too proud for my service shall soon enter hell abased." At the beginning of this verse, the phrase, 'odoo'ni call upon me' and after that the phrase 'IBadaat-service' is used, which shows that which is meant by call is a special request and a seeking of assistance before a being believed to have divine attributes.
Result: Of the three mentioned introductions, a result can be drawn out that the main goal of the Quran in these verses is preventing the supplication of the idol-worshippers who considered their idols as partners to God and possessors of intercession. Therefore, any other kind of submission, humiliation, help seeking or the seeking of intercession is prohibited; because they believed them being their small Gods that undertook their Godly works.
Furthermore, these idol-worshippers believe that God has assigned part of the works related to this world and the hereafter to them.
