(Wishing you well every year)
asalama laykum my dear sisters better sooner than later! let us fix ourselves and go back to the root of things.
“As for this closing reamrk, then it has no basis for it at all, it is sufficient for you (to say), “May Allaah accept your obedience.” As for “wishing you well every year,” this is a greeting of the non-Muslims which has crept into us the Muslims, due to our heedlesness, [Allaah says], “And remind, for verily reminder benefits the believers.”
“As for taking a specific phrase – wishing you will every year (kullu aaminwa antum bikhayr) – this has no basis, support from the Islamic Shari’ah, and is used in every Shari’ah, there is no difference (in this greeting) between a Jew, Christian and Muslim.”
