Does the frequent and continuous repetition of adhkar and prayers upon the Prophet (peace be upon him) contradict the Sharia?

Legitimate dhikr (remembrance of Allah) is of two types: unrestricted dhikr and restricted dhikr. Unrestricted dhikr is not bound by a specific time, place, or number, such as tasbeeh (glorifying Allah), tahmeed (praising Allah), tahleel (declaring Allah's oneness), and sending blessings upon the Prophet, peace and blessings be upon him. It is recommended to do this type of dhikr abundantly. Restricted dhikr is bound by a specific time, place, number, or method, such as the adhkar for prayer, sleep, morning, and evening. Sending blessings upon the Prophet, peace and blessings be upon him, is an unrestricted dhikr that has no limit. The more a servant does it, the better it is for him, as long as it does not distract him from an obligatory duty or something more virtuous.
