Hi Arun, is your family here with you in Resident permit. if No, then you cannot call your mother. If yes, then you can call your parents.
And you dont need tenancy agreement to call your mother in visit visa.
You need the following documents.
NOC letter from the company, which inlcudes your Salary letter also.
Yours and your Wife ID Card copy
Application form for visit visa.

I believe someone has mistakenly informed you about the Resident permit visa, where you need to submit the Tenancy agreement attested by baladiya etc, whereas for Visit visa you dont need these things.

Hope this helps.
