Some persons say that to utter "Ya Sheikh Abdul Qaadir Jilani Sha'in lillah" is Shirk because one is making partnership with Allah Ta’ala (committing Shirk) by asking for assistance from the creation of Allah Ta'ala. They say that one can only ask directly from Allah Ta’ala. The Ahle Sunnah Wal Jama'at believes that it is absolutely permissible to say "Ya Sheikh Abdal Qaadir Jilani Shai un lillah" when asking for assistance from those servants of Allah Ta'ala whom He has appointed as helpers of the Ummah.
We understand from the verse "Iyya ka Na'budu Wa Iy'ya ka Nas Ta'een" (You Alone we worship and You Alone we ask for Help), which is found in Surah Fateha, that the True Helper is Allah Ta'ala. But it is Allah Ta’ala who has appointed helpers from within His servants to assist the creation with His permission.
Sayyiduna Shah Abdul Azeez Muhaddith Delhwi (alaihir rahmah) explains the Tafseer of the verse "Iy'ya ka Na'budu Wa Iy'ya Ka Nastaeen" by writing: "Here, it should be understood that to ask for assistance from anyone other than Allah, by putting full trust and not thinking of it as a marvel of Almighty Allah, is prohibited. But, if the attention is towards Allah and then to think of a person as the splendour of Almighty Allah and by keeping the means and wisdom of Almighty Allah before you, if one asks from anyone other than Allah, then this is not far from the Wisdom of Almighty Allah. This action is permissible and allowed in Shari’ah. To ask for help in this way is not really asking from someone but Allah, but in reality it is to ask from Allah." (Tafseer Azeezi)
As long as a person bears this fact in mind that the True and Real Helper is Allah Ta'ala and no matter whom he asks from, it will be through the Mercy of Allah Ta'ala, then it is permissible to ask from such a person. This can never be termed as Shirk.
