Please don't complicate Islam brothers and sisters. By following the prophet's perfect character we should follow his morals, commands and values. If we think like this then all phrases we use in our daily lives will be considered as bida'h.

Here is a hadith from the Prophet: Abu Huraira reported: The Prophet, peace and blessings be upon him, said, “Verily, the religion is easy and no one burdens himself in religion but that it overwhelms him. Follow the right course, seek closeness to Allah, give glad tidings, and seek help for worship in the morning and evening and a part of the night.”
