Salutations.
Yes, Muslims are welcome at Christian Forums.
There are forums that are dedicated to Christian use, and those are clearly marked. Hopefully Christians who visit there exhibit the spiritual "fruits" our God asks of us: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. I fear that many of us fall short of those ideals, and I pray that no one here diminishes your opinion of us through their behavior.
Your profile indicates that you are married. Is your wife a speaker of English? If so, there are many "threads" that she may enjoy. I now have friends who garden and can teach me more, who read books that we may discuss, and who are writers. Your wife might enjoy these as well. Please extend an invitation to her on my behalf.
When I was teaching, I taught a male student who was an Egyptian Muslim. He was well-liked and respected by his peers. He also was respectful to me and was diligent in his studies. I was proud that he was my student.
Again, welcome. Read through the FAQ ("click" on the bottom blue bar above the forum area, 3rd topic from the right). Many of your questions will be answered there. I hope you will enjoy the "games" we play here to earn "blessings" to use as currency for icons on our personal posts, and "reputation".
May you find this site a "blessing".
Mrs. ConstanceB
