الجواب حامدا و مصلیا
Allahتعالی rewards one who looks at his parents with eyes of mercy with the rewards of an accepted Nafl Hajj. If on this basis, one says to his mother “You are my Hajj,” then there is no sin in that. However, it is not proper for one to call his mother such names, and this should be avoided.
And Allah knows best.
