Inshallah i will ask all those questions today and post back the finding getting reference to any hadees etc put forward by them.
Shah Waliullah muhaddith dehalvi [rh] writes in his book ‘Al Intibah fi Salasil ul Auliaullah’ that he received the ijaza [permission] in Sattariya silsila [ tariqa] He gives the chain of this ijaza contaning names of different scholar including Ghaus Gwaliari who was the chief of Sattariya silsila in India.
Shah Waliullah writes that through this chain he received the’Aurad and wazaif ‘ of Sattariya silsila which includes Dua e saifi and Jawahir Khamsa.
Dua e saifi is a supplication which is taught to mureed by a shaykh who has ijaza to recite and teach this dua. The last part of Dua e saifi consists of Nad e ali which has words like “ Ya Ali , Ya Ali , Ya Abu Turab”.
