Taken from “Furu-ul-Iman: Branches of Iman” By Mawlana Ashraf Ali Thanvi rahimahullah
Unity or Oneness of Existence of Allah [Wahdat-ul-Wujud]
In this terminology of Sufi sect, there is a third meaning of Tawheed aswell.
“No one is existing except Allah.”
This is called unity of existence (Wahdat-ul-wujud). To prove this meaning from Qur’an and Hadith is useless and wastage of time. It is sufficient to describe this in such a way that it does not contradict Qur’an and Hadith. This has become a problem these days. Since the issue is very delicate and the basis of its proof is only on Zoaq (Spiritual taste) and Kashf (Divine manifestiation), so it is very difficult to get the proper words to express this thing and secondly whatever little or more interpretation is possible, it needs spiritual taste or Zoaq, congeniality with divine manifestiation or Kashf and great depth in religious knowledge so that one can understand it.
These days one gets extremely pained to see most of the so called claimants of Wahdat-ul-Wujud of today, They have neither knowledge nor the spiritual fervour. Their job is just vainful talk of pseudomystics without bothering to understand that these heretic and atheistic words which they are talking about will deprive one of his Iman. Neither they understand that other people who will follow them blindly will also start claiming the same, and will lose their Imaan, whatever, little they will be having, they will stop offering Salaat and observing fasts, thinking that they have become god, then what for Salat and Saum-Allah forbid.
Unity of existence of Allah (Wahdat-ul-Wujud) never meant this, in fact it is a state understood by only those who experiance it. It should neither be uttered purposely by tongue nor can other people understand it.
When this ecstasy dominates a person, his condition states:
“Accommodated as you are in my eyes. Wherever I see, there only you and you.”
Sometimes this state remains permanent and sometimes vanishes, InshaAllah at some other time, we will discuss this issue in some detail, here I stop with this sincere advice that for Allah’s sake have mercy at your own life and at the Ummatt-e-Muslima and do not indulge in excessive exaggerations about this issue.
To be very safe one should not believe it with certainty even after Kashf because there always remains a chance to err so far as the Kashf is concerned. One should remain busy with the things which is needed and that is servitude. One should forget talks with no substance.

Deeds not strength matters in mystic way
Strength does not come without deeds!
