29 - Ibni 'Abidin 'rahmatullahi alaih' in discussing the makruhs of namaz says: "Things which disbelievers do and use are of two types: The first ones are things which they do as customs, that is, things which each nation, each country does as its customs. Out of these, doing or using things that are not haram and that are useful is never a sin. [Using trousers, fez, different types of shoes, spoons and forks, eating meals at a table, putting each person's meal in a dish in front of him, cutting the bread in slices with a knife, and using various tools and gadgets are all behaviors concerning customs and are mubah. It is not a bidat or a sin to use them.] Rasulullah put on shoes especially made for priests." Among them, doing or using the ones that are unpleasant and loathsome and which are not useful is haram. But, after two Muslims use them, they become (Islamic customs) and are not haram for the third Muslim who uses them. The first and second Muslim become sinful, but not the others. In the book Qamus-ul-alam, in the passage giving information about Timurtas Pasha, it is written: "Timurtas Pasha is the person who designed the color of the Ottoman Banner. [Also, the shape of today's Turkish flag with its crescent and star.] He also colored the faz red, which had been white up until that time." The color of the Abbaside State's flag was black. It was changed to white during the time of khalifa Mamun. As it can be seen, the fez was not taken from the Hungarian people, but rather, it was developed by the Turks.

It is written in Birghiwi Vasiyyetnamesi Sharhi [Muhammad Birghiwi Bey's father is Ali. He was born in Balikesir in 928 and died of the plague in 981 A.H. His works, Vasiyyetname, Tariqat, Awamil and Izhar and others, are very valuable.], "The second type of things which disbelievers use are the things which are symptoms of disbelief, symptoms of denying and disbelieving the Shariat and Islam, and it is wajib for us to debase them. One who does or uses them becomes a disbeliever. They cannot be used unless one is threatened with death or with the cutting off of one's limbs or some other reasons causing these results such as severe thrashing or imprisonment or the taking away of all one's property. Also, he who does or uses one of them, which is commonly known, without knowing or as a joke in order to make people laugh, becomes a disbeliever. For example, it is kufr to wear (or use) things specially worn or used by priests during their worships. This is called Kufr-i hukmi." It is written in the basic books of fiqh by Islamic 'alims that to wear the 'things that are peculiar to disbelievers is kufr. (See Ibn-i 'Abidin, Vol. V, page 481). The enemies of Islam, in order to deceive Muslims, try to hide the fact that it is kufr to adopt the customs of the disbelievers and to celebrate their festivals. They call these customs 'Islamic customs' and these days 'sacred days'. They represent the Noel (Christmas), which was introduced into Christianity by the Great Constantine, and Nawruz, which was invented by Jamshid as a national celebration; and they want Muslims to accept the same things. Young and innocent Muslims should not fall for these things. They should learn the truth by asking those sincere Muslims they trust, their relatives who perform namaz, and those family friends who know their religion. Today, no matter where in the world, not to know what is iman and what is kufr or how to perform 'ibadats correctly is inexcusable. He who is deceived because he does not know his din will not be saved from Hell. Today, Allahu ta'ala has made His din known everywhere in the world, and He has made learning iman, the fards, the harams and the halals, beautiful morals very easy. Everybody should learn as much as necessary and this is a fard. One who does not learn them is deemed to have disobeyed the fard. But a person who says there is no need to learn them or who gives no importance to them becomes a disbeliever.
