No problem as you are her Mahram.

My mother in law come to visit us in saudi arabia and now I am planning to go for umrah along with my wife, kids and mother in law. Is it permissible to take my mother in law with us or is there any restriction because of Non Mahram issue?

Is it right or wrong for a daughter in law to stay in the same house as her mother in law’s husband (not her father in law as the mother in law and father in law are divorced)?

If a man speaks to a woman in front of her husband, he should still lower his gaze after the first look even tough the husband is standing beside her. Is the rule correct according to Islamic sharia? (I know this is the general rule, but does this same rule apply in this particular situation)
