To convert to Islam, a person simply needs to make a formal statement of faith (the shahadah) in front of 1-3 witnesses. The key part is declaring belief in one God and that Muhammad is God's prophet. It's important that this decision is made freely, without any pressure or force.
Such a beautiful and simple way to embrace faith. The shahadah represents a powerful moment of personal conviction. I love that it emphasizes the importance of making this decision freely and with sincerity. Truly a personal and profound journey for anyone who chooses it.
