As a human being, If you make a mistake, you make an error, a blunder or you do something perhaps that might not have been the best way of doing things, Quickly learn to apologise, learn to come forth and make amends; Learn to seek forgiveness not only from those whom you’ve wronged but from Allah (swt) primarily because you know I have to go back to my Lord, He made me. I’m going to answer to Him.
You’re getting married to someone and that person is the child of someone and they have a family and they have a loving family and they’ve been treated with kindness and goodness throughout their lives. Treat them in a similar, if not better way.
The tongue in marriage will make or break it.
Whoever follows Allah and His messenger has indeed succeeded the great success.
Your connection with Allah is closely related to how you address the rest of the creatures of the same Allah.
