What is the Prophetic guidance regarding condolences, Eid greetings, and supplication for one who has prayed and performed ablution, apart from common phrases such as "May Allah accept [your prayers]," "May you be well every year," "May Allah magnify your reward," and "Zamzam"?

The Sunnah in offering condolences is to say: "To Allah belongs what He takes and to Him belongs what He gives, and everything with Him has an appointed term." The bereaved person responds by saying: "May Allah reward you."

The Sunnah in offering Eid greetings is to say: "May Allah accept from us and from you."

As for the supplication after prayer or ablution by saying "Haraman" or "Zamzam," this was not from the guidance of the Prophet (peace be upon him). Adhering to these phrases as an act of worship is among the blameworthy innovations. However, saying it occasionally without commitment is permissible.
