Radiallahu anha or Alahi wasllam for Mariam?

In Islamic tradition, both phrases are used to show respect and honor towards significant figures. For Maryam (Mary), the mother of Isa (Jesus), the phrase "Radiallahu anha" is often used, which means "May Allah be pleased with her." This expression is typically used for female companions of the Prophet Muhammad ﷺ and other revered women in Islam.

Additionally, when mentioning Maryam, it is also common to say "Alaiha assalam," which means "Peace be upon her." This phrase acknowledges her status as a revered and pure figure in Islam. In the Qur'an, she is described as being chosen and purified by Allah, as noted in the verse: O Mary! Lo! Allah hath chosen thee and made thee pure, and hath preferred thee above (all) the women of creation. 3:42.

Both forms of respect are appropriate and reflect her esteemed position in Islam.
