Is there not a hadith narrated from the Chosen One (peace be upon him) stating that Allah forgives in the middle of Rajab for anyone who associates nothing with Him, and what are the hadiths mentioned regarding "there is no might nor power except with Allah"?

No particular authentic hadith has been reported regarding thevirtues of the month of Rajab. The narrations mentioned about it are weak and fabricated, by the consensus of the people of knowledge. As for the virtue of the middle of Sha'ban night, an authentic hadith has been reported from the Prophet, peace and blessings be upon him, which is his saying: "Indeed, Allah looks down on the middle of Sha'ban night and forgives all His creation except for a polytheist or one who harbors malice." As for the hadiths reported about the virtue of "La hawla wa la quwwata illa billah" (there is no might nor power except with Allah), they are numerous, among them that it is a treasure from the treasures of Paradise, and that it expiates sins, and that it is said upon leaving the house to suffice and protect from Satan.
