Answer:
Whenever a translation of the Qur'an is written ( because there are no upper and lower case letters in Arabic ) the translator will usually capitalize every term that refers back to Allah. So, for example, if the Qur'an says that Allah, "He" says such and such, then the "He" is capitalized because this refers to Allah.
Likewise, the word in Arabic, "Nahnu", which means 'we' is capitalized when Allah is referring to Himself in the Royal We. Just as the Queen of England (though she is nothing at all but a mortal human being who actually has no more worth than anyone else) says: "We, the Queen".
Allah also says "We" created, We ordained, We guided, etc. etc.
