One of the most important characteristics, frequently mentioned with regards to the Prophet (saas) in the Qur'an, is that he only practiced what Allah revealed and asked of him, with no concern about what others might think. Important figures and members of other religions at the time wanted him to impose rules that would benefit them. Although these people were more numerous and powerful, the Prophet (saas) was punctilious about abiding by Allah's commandments and the Qur'an. Allah tells us the following in one verse:

When Our Clear Signs are recited to them, those who do not expect to meet Us say, "Bring a Qur'an other than this one or change it." Say: "It is not for me to change it of my own accord. I follow nothing except what is revealed to me. I fear, were I to disobey my Lord, the punishment of a Dreadful Day." Say: "Had Allah so wished, I would not have recited it to you nor would He have made it known to you. I lived among you for many years before it came. Will you not use your intellect?" (Surah Yunus: 15-16)

In a number of verses of the Qur'an, Allah warned the Prophet (saas) about the conduct of his people. For instance:

And We have sent down the Book to you [Muhammad] with truth, confirming and conserving the previous Books. So judge between them by what Allah has sent down and do not follow their whims and desires deviating from the Truth that has come to you. We have appointed a law and a practice for every one of you. Had Allah willed, He would have made you a single community, but He wanted to test you regarding what has come to you. So compete with each other in doing good. Every one of you will return to Allah and He will inform you regarding the things about which you differed. Judge between them by what Allah has sent down and do not follow their whims and desires. And beware of them lest they lure you away from some of what Allah has sent down to you. If they turn their backs, then know that Allah wants to afflict them with some of their wrong actions. Many of mankind are deviators. (Surat al-Ma'ida: 48-49)

The Prophet (saas) told people repeatedly and determinedly to do nothing but that which Allah had revealed to him. One verse concerning this superior morality of the Prophet (saas) reads:

Say: "I do not say to you that I possess the treasuries of Allah, nor do I know the Unseen, nor do I say to you that I am an angel. I only follow what has been revealed to me." Say: "Are the blind the same as those who can see? So will you not reflect?" (Surat al-An‘am: 50)

Alongside that determination and constancy in the way of Allah, the Prophet (saas) told people about the true religion in the best and most pleasing manner. Comparing the Prophet (saas) to the great majority of people will be very helpful in understanding his superior qualities. Most people, now as in the past, are consumed with desires, longings and passions. Although the great majority believe in religion, they are unable to overcome those obsessions. Instead of giving up those desires, they make concessions when it comes to their religious obligations. They fail to carry out some of those obligations out of concern, for instance, over what their spouses, relatives or friends might say. Or, they are unable to give up habits that are unacceptable to the religion. They therefore interpret religion according to their own interests, accept those rules which suit them, and reject those which do not.

The Prophet (saas) never made any concessions to what such people wanted. He conveyed the Qur'an to mankind with no alteration to what Allah had revealed, taking no one's personal interests into account, and did so simply in the spirit of fear of Allah. Allah speaks of the Prophet (saas)'s godliness (taqwa) in the Qur'an:

By the star when it descends, your companion is not misguided or misled; nor does he speak from whim. It is nothing but Revelation revealed, taught him by one immensely strong, possessing power and splendour [i.e., Gabriel]...(Surat an-Najm: 1-6)

Know that the Messenger of Allah is among you. If he were to obey you in many things, you would suffer for it.However, Allah has given you love of faith and made it pleasing to your hearts, and has made disbelief, deviance and disobedience hateful to you. People such as these are rightly guided. (Surat al-Hujurat: 7)
