Shaykhul Islam Ibn Taymiyyah rahimahullah mentions the following at the end of his book “al-aqeedah al-waasitiyyah”:
…[Ahl as-Sunnah] They call on people to practice noble manners and good deeds, and to indoctrinate themselves with the Prophet’s saying:
“A perfect faith belongs to a believer with good manners.” (Reported by Ibn Hanbal and at-Tirmidhi who said it is good and sound hadith)
…[Ahl as-Sunnah] urge people to mend the relations with those who have broken with them, to give to those who have deprived them, and to forgive those who have done injustice to them. They order people to keep filial piety, to be good to other relatives, to be good neighbors, to treat orphans, wayfarers and the poor kindly and to be gentle and humane to the slave. They forbid bragging, arrogance and transgression. They prevent people from feeling superior over others, rightly or wrongly. And they bid people use high manners and prohibit them from pursuing trifles. All that they say or do of the above, or of other than it, in all of it they follow the Book [The Qur’an and the Sunnah. Their “path” is the religion of Islam, for which Allah sent Muhammad (peace be upon him)…]
Note: An important section found in a popular aqeedah book. I fear this section of the book has been overlooked by many and Allah’s aid is sought. They say Shaykh Islam wrote these words when he was around 38 years old.
