“May Allah accept it,” or “acceptance.” This is an innovation; the Companions never did such a thing. It is enough for the worshipper, when he ends the prayer, simply to turn to his right and to his left saying, “Peace be upon you and the mercy of Allah.”
As for bowing when meeting someone, or embracing and locking arms, the Prophet ﷺ was asked: “Should one bow?” He replied, “No.” The questioner then asked, “Should he clasp him and embrace him?” He replied, “No.” Thus, when a man meets his brother he should not clasp him—meaning he should neither pull him close, nor embrace him, nor bow to him. Bowing is even more serious and blameworthy, for it contains a kind of submission to other than Allah similar to the bowing (rukūʿ) performed for Allah in prayer; therefore it is forbidden. Rather, he should simply shake his hand, and that suffices—unless there is a specific reason, in which case hugging or kissing is permissible, such as when someone returns from a journey or the like.
