Starting from all the prophets, all the sahaba karam and their followers like Aulia-Karam etc,all are good spirits.
I will quote hadith/ayat for your reference.
ALLAH says about his servants in surah Al-Kahf: (18:28)
"Stay tenaciously in the companionship of those who remember their Lord morning and evening, ardently seeking His pleasure, (keen on the glimpse of His sight and eagerly aspiring to glance at His radiant Countenance). Your (affectionate and caring) looks must not but focus them. Do you seek the charisma of the worldly life (shifting your attention away from these self-denying devotees)? And (also) do not follow him whose heart We have made neglectful of Our remembrance and who follows but the urge of his (ill-commanding self) and his case has exceeded all bounds. "
This is being said about Aulia-Karam, how? because their life posseses these qualities as narrated in the ayat.Since they lived a life only on orders of ALLAH, they are good human beings.
A hadith (actually it is Hadith-e-Qudsi) from Sahih Bukhari Shreef.
Bukhari sharif Volume 8, Book 76, Number 509:
Narrated Abu Huraira:
Allah’s Apostle (peace be upon him) said,
“Allah said, 'I will declare war against him who shows hostility to a** pious worshipper of Mine.** And the most beloved things with which My slave comes nearer to Me, is what I have enjoined upon him; and My slave keeps on coming closer to Me through performing Nawafil (praying or doing extra deeds besides what is obligatory) till I love him, so I become his sense of hearing with which he hears, and his sense of sight with which he sees, and his hand with which he grips, and his leg with which he walks; and if he asks Me, I will give him, and if he asks My protection (Refuge), I will protect him; (i.e. give him My Refuge) and I do not hesitate to do anything as I hesitate to take the soul of the believer, for he hates death, and I hate to disappoint him.”
I am Talking about Pir in terms of Awlia-Karam. I didnt say Molvi.
The Holy Prophet (sallal laahu alaihi wasallam) has stated,
“There are certain of Allah’s servants that have been set aside to fulfil the necessities of the people. People will call to them in their times of need. They are protected from the punishment of Almighty Allah”. (Jame Saghir)
And in Koran, its written:
“Your helpers are Almighty Allah and His Rasool and those Muslims who perform Salaah and give alms and make Ruku” (5:55,Koran)
I dont really pursue logic most of the times because some site ,i think on wiki-islam , i was reading about the people who very proudly left islam and converted to atheists or some another, 90% had put the reasons as LOGIC.
What makes sense to me asking for waseela is that, Hazrat Muhammad (SAW) asked Hazrat Awais Qarni (R.A) to make a dua for the forgiveness of His(SAW) Ummah to ALLAH.
I am in no way, asking you to agree with me. Its your free will and i respect that. I am merely sharing what i know and im sharing that in context of Koran and Hadith.
100% agreed without any doubt.
