alBHAGDADI:
Adding her father's name to her husband's name is totally against the Bible. Including her father's name means her marriage, which her father should have no business in, now includes him. This makes it two flesh.
Genesis 2:24
Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
It also doesn't show submission which is against the Bible which says wives should submit to their husband. It changes the ancient landmark which we all met.
And answer to one name? Like if the man's first name is Segun, she starts bearing Segun too, in the Spirit of submission and "two become one"?
