In The Name of Allaah, The Most Merciful The Bestower of Mercy
Al-Allaamah Aloosee (rahimahullaah) continued…….
And amongst the traits of the people of the era of the pre-Islamic era of ignorance is that:
They used to carry out worship whilst associating the righteous people as partners to Allaah in worship. They regarded this to be an elevation of the (righteous people) which Allaah loves. Also they intended (through this worship of the righteous people) to get closer to Allaah and to attain success by seeking their intercession; because they thought that the (righteous people) were pleased with them for carrying out such acts. Indeed, the Qur’aan has informed us of this trait of theirs, and He (The Most High) said:
‘’Verily, We have sent down the Book to you (O Muhammad) in truth: So worship Allah (Alone) by doing reli-gious deeds sincerely for Allah’s sake only, (and not to show-off, and not to set up rivals with Him in worship). Surely, the religion (i.e. the worship and the obedience) is for Allah only. And those who take Auliya’ (protec-tors and helpers) besides Him (say): “We worship them only that they may bring us near to Allah.” Verily, Allah will judge between them concerning that wherein they differ. Truly, Allah guides not him who is a liar, and a disbeliever.’’ 
Their worship of the righteous people was that they supplicated to them and sought their needs from them. They slaughtered sacrifices, vowed and gave oaths for the sake of the (righteous people). Allaah (The Most High) said:
”And they worship besides Allah things that hurt them not, nor profit them, and they say: “These are our intercessors with Allah.” Say: “Do you inform Allah of that which He knows not in the heavens and on the earth?” Glorified and Exalted be He above all that which they associate as partners with Him!’’ 
This is the greatest affair in which the Messenger (sallal-laahu-alayhi-wasallam) opposed them. (That is) because he (sallal-laahu-alayhi-wasallam) came with the religion of Ikhlaas (i.e. to purify one’s worship for Allaah alone), and he informed them that this is the religion of Allaah besides which no other religion is accepted. He (informed them) that whoever does what he (merely) deems to be correct, then indeed Allaah will forbid him from entry into paradise and the fire of hell will be his destination. This (sincerity in worshipping Allaah alone) is what the entire religion is (based upon); and because of it, the people are divided into Muslims and disbelievers; and because of it there occurred enmity between the people and Jihaad was legislated. Allaah (The Most High) said:
‘’And fight them until there is no more Fitnah (disbelief and polytheism: i.e. worshipping others besides Allah) and the religion (worship) will all be for Allah Alone.’’ 
And that which is well known is that the extremist (soofees and worshippers of graves) have an ample share of this trait of those who preceded them (in worship of the righteous people and the graves). This has been witnessed.
