In the book: Fada’il al-A’mal, first edition 1994 of the English translation. On the end of page 21 of Virtues of Salah, you will find the words ascribing kasha of “seeing sins falling down from the limbs of the person performing wudu…” to Imam Abu Hanifah (rahimahullah). Kashf means, in Khandhlawi’s own words, “divine manifestation of unseen things”(pg.128 of Virtues of Dhikr).
Muslims know that seeing the unseen (ghayb) is only possible to Allah, and the claim and lie that people are able to do such things is clear shirk. And on top of that it is a lie on Imam Abu Hanifah (rahimahullah).
