Ireceived this text with his hadith and it didnt have a reference. and Alhamdoulillah i just fell on an article saying this hadith is actually fabricated.

What is the opinion of Hadith scholars on the following Athar (narration from the Companions): “Rajab is the Month of Allah, Sha‘ban is my month and Ramadan is the month of my Ummah (nation based on one creed)”? And is this a Hadith Sahih (authentic Hadith): “O Allah! To You do I complain of my weakness, my helplessness, and disregard of people towards me...”?
A: Firstly: The narration, “Rajab is the Month of Allah, Sha‘ban is my month and Ramadan is the month of my nation” is a Hadith Mawdu‘ (fabricated Hadith). The Sanad (chain of narrators) includes Abu Bakr ibn Al-Hasan Al-Naqqash who is accused of fabrication, and Al-Kisa’y who is unknown and his name was mentioned in "Al-La'ali' fy Al-Mawdu`at" book about fabricated Hadiths.
(Part No. 3; Page No. 208)
Secondly: The Hadith: O Allah! To You do I complain of my weakness, and my helplessness, and disregard of people towards me. O Most Merciful of the merciful! You are the Lord of the oppressed, and You are my Lord. To whom do You entrust me? Is it to a stranger, who would frown on me? Or is it to an enemy, to whom You have given mastery over me? If You are not angry with me, then I do not care. But Your Protection is the more all-embracing for me. I seek refuge in the Light of Your Face, whereby all darkness has shone, and whereby the affairs of worldly life and the Hereafter have been set right, lest You should send down upon me Your Anger, or Your Wrath should befall me. Yours Alone is the right to blame until You are Content, and there is neither power nor might except with You. This Hadith is Da‘if (weak; a Hadith that fails to reach the status of Hasan) due to a weakness in the Sanad.
May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family, and Companions!

the stuff not in bold is just part of the question but not relevant to my blog.
