What is the ruling on saying: "O Allah, breathe into Your morning the spirit of our hopes"?

It is best to stick to the ma'thur (traditionally transmitted) supplications and the وردت (narrated) phrases. However, there is no harm in this supplication, "Breathe spirit into our hopes" (انفخ روح أمانينا); its apparent correct meaning is a request for the realization of hopes, and what is intended by it is: "Grant us what we wish for." The supplication is similar to what is stated in the Hadith: "Indeed, the Holy Spirit breathed into my heart," meaning: He inspired and cast (it into my heart).
