Is it necessary for someone who has prayed the Duha prayer to pray it always?

Scholars have differed on the ruling concerning the Dhuha prayer, holding six different opinions. The most preponderant among them is that it is recommended (mustahabb) due to the encouragement received regarding it, for it suffices for 360 acts of charity. Therefore, whoever consistently performs it has loved this great good and abundant reward, and whoever does not perform it incurs no sin. What is popular among common people, that whoever prays it then abandons it will go blind, has no basis.
