Of course, a believer should be open to advice. A Muslim might make a mistake, there is nothing wrong with this but he should always pay heed to advice of others: In other words, a Muslim shouldn't be arrogant, disrespectful and snobbish, right? Even though he won't follow the advice, he should politely listen to it within the limits of the Qur'an and say, "I will try hard to do so." - Harun Yahya
