Miftahul Ma'ruf (Arabic: معروف) is an Islamic term meaning that which is commonly known or acknowledged. The word is most often found in the Qur'anic exhortation. "Amr bil Ma'ruf wa Nahy an al Munkar (امر بالمعروف و نهى عن المنكر)." This is often translated as "Command the good and forbid the bad," but this translation fails to reflect the subtleties of the Arabic. Amr refers to the enforcement function of the duly constituted government of an ummah (community). In this context, Ma'ruf, when applied to a particular law, means a law which is:
There is a hadith in which Muhammad is quoted as saying, "My ummah will never agree upon an error." This has been interpreted to mean that the consensus of the community is a source of moral and legal authority.
There is also another verse in Quran, that says (( والاقربون أولى بالمعروف)), this is often translated as “ those who are close to you--or relatives--have priority for good deeds”.
Ma’ruf is also the name of a US-based Muslim organization that advocates social justice by serving individuals, families, and communities in need.
