Is it legislated to say the supplication: "O Allah, make every deed I do purely for Your Noble Countenance, and grant me reward and recompense for it. O Allah, help me and help my family and all Muslims to remember You, thank You, and worship You well," daily in the morning to make daily deeds acts of worship?

This supplication, part of which is quoted from the Sunnah, is well-constructed and sound in meaning. There is no منع (prohibition) against supplicating with it, or with parts of it that are easy to recite, at any time or place, for Allah has commanded us to supplicate and promised to answer. It is preferable for a Muslim to supplicate with what is mentioned in the Quran and the Sunnah.
