No. Muslims are about two billion people with different cultures, schools of law, political views and levels of practice. They agree on the basics of faith, and differ on many details, as members of any large community do.
The fuller answer
There are Sunnis, Shias, Ibadis, Sufis and others, and four main Sunni schools of law that differ on points in prayer, fasting and finance. Some Muslims are strict in practice, others are relaxed, and some are Muslim in name or culture only. A Muslim from Malaysia can differ greatly from one in Morocco or Michigan in customs and dress.
That is why it is wise to ask a Muslim about their own view and not to treat what one person says as representing everyone. The Quran itself says that people were made into nations and tribes to know one another.
O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted.
And We have revealed to you, [O Muhammad], the Book in truth, confirming that which preceded it of the Scripture and as a criterion over it. So judge between them by what Allah has revealed and do not follow their inclinations away from what has come to you of the truth. To each of you We prescribed a law and a method. Had Allah willed, He would have made you one nation [united in religion], but [He intended] to test you in what He has given you; so race to [all that is] good. To Allah is your return all together, and He will [then] inform you concerning that over which you used to differ.
This answer follows the mainstream Sunni understanding and is general learning, not a fatwa. Where Muslims differ, the answer says so. Have a question of your own? Write to us.
