An interesting find on the site. http://www.daralhadith.org.uk/wp-content/uploads/2015/07/Barzanji-Ilm-Ghayb.pdf Shaykh ahmad barzanji's treatise on 'Ilm ul ghaib. Deobandis present another work of shaykh barzanji's whose original manuscript is unknown and gives an inaccurate representation of shaykh barzanji's views on ilm ul ghaib. Mufti monawwar atiq of the UK explains this https://scholarsink.files.wordpress.com/2011/06/knowledge_of_the_unseen_theology1.pdf (pages 27 and 28). He mentions the work Risalah fi al-Ilm al-Nabawi. is that the same as the work above (Risalah fi ilm al ghaib)?
