Here are few things to keep in mind before you have “the talk” about your conversion:

Don’t make assumptions

Usually, people make the assumption of expecting the worst of one loved ones. One presumes they’d all react negatively to one’s decision, and that could make one defensive and anxious from the beginning. If you start off the discussion with the assumption that your family and friends will be unsupportive or hostile, they will pick up on your attitude, and this will sabotage the mood of the conversation.
Instead, try to convey calmness, positivity, self-assurance, and optimism. Maybe the conversation will go really well!

Don’t make it sound like you’re sharing bad news.

If you start your announcement with a somber, “Please sit down. There’s something I need to talk to you about,” your loved ones might panic.
Instead, stay upbeat. After all, embracing Islam is something to celebrate. Saying, “I have some exciting news to share with you!” will start things off on a much better note.

Prepare ahead of time.

You might want to write down some notes to remember the key points you want to share with your loved ones. Try to foresee some of their questions and concerns and address these in your delivery. Without being too preachy, share some of the things you love about Islam and how you expect it will change your life for the better.
Make it clear that this is your choice and that it was made after much deliberation, research, and soul-searching.

If, despite your best efforts, your loved ones still react in a negative way, don’t lose hope. Keep in mind that fear is behind most of their emotions and reactions. They might act shocked, argumentative, unsupportive, judgmental, disbelieving, or a variety of other reactions, but behind all of these emotions, it is apprehension.

What are they afraid of? Change can be scary for many people. They might worry that you’ll become a different person altogether and that you’ll grow apart from them. They might conclude that your conversion to Islam will affect their own life in some detrimental way. They might start listing all the things they think you will be deprived of, such as dating, alcohol, pork, and wearing revealing clothing. Depending on their religious beliefs, your loved ones might worry about the fate of your soul. In their ignorance, they might even fear that you’ll be “less Modernize” (or less whatever) as a Muslim. Much of this anxiety is fueled by a lack of knowledge, which brings us to the next point.
