How Does One Become a Muslim?

The non-Muslim embraces Islam by believing in the Two Testifications of Faith and uttering them with the intention of leaving out blasphemy.
1. The first Testification means that no one or thing deserves to be worshipped except God Who is the Creator of everything.
2. The second Testification states that Muhammad the son of ^Abdillah who was born in Makkah about 1400 years ago is a messenger of God. He was sent to convey what God revealed to him so that the humans believe in and work with the Laws he received and brought. He is truthful in all what he conveyed.
The Two Testifications reject the Godhood of anyone or anything other than God. They confirm the Godhood of God only with the acknowledgment of the message of prophet Muhammad.
كيف يدخل غير المسلم في الإسلام
يَدخل غيرُ المسلم في الإسلام بالإيمان بمعنى الشهادتين وقولِهِما سامعًا نفسَه بأيّ لغةٍ يُحسنها.
وإن أراد قولَهما بالعربية فهما: أَشْهَدُ أَنْ لا إلَـهَ إلَّا اللهُ، وَأَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ الله
وإن شاء قال: لا إلَـهَ إلَّا اللهُ، مُحَمَّدٌ رَسُولُ الله
