Is the continued recitation of Surat An-Nasr 10 times and prayer upon the Prophet 11 times every morning for 7 days, for the purpose of attracting customers and bringing blessings to a shop, correct?

Dhikr (remembrances of God) prescribed with specific numbers and days for attracting sustenance and blessings is not legislated, due to lack of evidence for it. There is no specific dhikr or surah (definition) (chapter of the Qur'an) designated for this purpose. It is legislated for a Muslim to ask Allah for good and blessed sustenance, and to supplicate with prophetic supplications without restricting them to a specific number or time, such as: "O Allah, I ask You for beneficial knowledge, good sustenance, and accepted deeds," and "O Allah, forgive me, guide me, grant me sustenance, and grant me well-being. I seek refuge in Allah from the constriction of standing on the Day of Resurrection."
