Are these ahadith regarding reciting "Allah is sufficient for me..." seven times authentic?

Assalamu alaikum. Recently I have seen the following excerpt which I'm copying here... > Hasbiyallaahu laa 'ilaaha 'illaa Huwa 'alayhi tawakkaltu wa Huwa Rabbul-'Arshil-'Adheem. > > Allah is sufficient for me. There is none worthy of worship but Him. I have placed my trust in Him, He is Lord of the Majestic Throne. (Recite seven times in Arabic.) and > Allah will grant whoever recites this seven times in the morning or evening whatever he desires from this world or the next, Ibn As-Sunni (no. 71), Abu Dawud 4/321. Both reports are attributed directly to the Prophet (Marfu1). The chain of transmission is sound (Sahih). Ibn As-Sunni." My question is I have previously read about this Hadith where it states that it is fabricated. But now as I see the above mentioned excerpt in two different sites I am confused. Can anyone tell me which one is right? I mean is it really fabricated or is there any level of authenticity in it? Also please mention some authentic Dua for getting out of distresses and fulfillment of wishes.
