Why are the phrases "Jumu'ah Mubarakah" considered an innovation (bid'ah), and the phrases "Zamzam" and "Haraman" considered an innovation and apostasy, because they were not narrated from the Prophet (peace be upon him) or his companions (may Allah be pleased with them), while the saying of the companions (may Allah be pleased with them) on the day of Eid, "May Allah accept from us and from you," is not considered an innovation, even though it was not explicitly narrated from the Prophet?

Innovated phrases are considered bid'ah (innovation) if adhering to them is done as an act of worship and with the belief in their Sunnah status. However, if they are not continuously practiced or not considered an act of worship, then they are not deemed bid'ah. The actions of the Companions that were widespread among them and not disavowed by any of them are considered a proof. A Muslim must be aware of the danger of innovation and be keen to follow the Sunnah, learn it, adhere to it, and call others to it.
