As explained in the first part of the topic, Islam has spread much more quickly compared to other religions all over the world. The traits of Prophet Muhammad (PBUH&HP) were introduced as one of the reasons. Here, the effect of the scientific and social interactions with the rest of the world throughout the Islam's history is discussed. 

 As an introduction, it is good to know that Islam has adopted two types of regulations; confirmed rules and established ones. The Islamic approach regarding the confirmed rules -the regulations which existed before and were conserved or revised if needed- is one of the keys to the development and permanence of Islam. And, this will be the focus of this article.   

Saying Yes to the Good Costumes throughout Islam's History

The Islamic approach to the habits and rules that were common in the pre-Islamic era was that it neither opposed them totally nor accepted them entirely. In some cases, Islam has affirmed and preserved some rules. That was when those rules or customs were not in contradiction to the social order and the living facilities of humans or in case of the righteous customs and traditions that existed before the emergence of Islam; e.g., some of the rules on making contracts. 

However, some of the useful regulations required to be revised and this was accomplished by adding some conditions. On the contrary, some customs and routines were opposed and removed due to the bugs and disadvantages or because they were manipulated or misused for personal benefits; e.g., usury (Riba) [1].

The rules conserved by Islam, such as those about the ownership and property, are called confirmed rules. On the other hand, the rules instituted by the Islamic jurisprudence which never existed before are called established rules [1]. This demonstrates that Islam has always been in constant interaction with the world, and the positive aspects of human societies are considered. Hence, the message of Islam and its framework have not been far from what people are familiar. This consequently has made it easier to accept Islam.

Seeking knowledge; A Way to Spread Islam

Islam has urged everyone to seek knowledge. The first verse of the Quran revealed to Prophet Muhammad (PBUH&HP) enjoined reading which is the key to knowledge: “Read in the Name of your Lord who created” (96:1). Literacy and having knowledge are so important in Islam that Quran equals illiteracy to being in darkness. According to Prophet Muhammad (PBUH&HP), seeking knowledge is obligatory (Wajib) for every Muslim and God loves those who seek knowledge [2].

Learning and seeking knowledge have been emphasized such that Muslims have been encouraged even to travel in order to learn things. Imam Ali (AS) recommended traveling to acquire privilege and named gaining knowledge as one of the achievements of traveling [3]. Prophet Muhammad (PBUH) advised seeking knowledge even if for that purpose one should go to the lands far away [4].

The Holy Quran also addresses the believers as those who are not affected by the wrong behaviors of others since they have been guided. So, the believers can peacefully learn from the positive aspects of others. Another proof of the attention paid to knowledge in Islam is that Muslims used to release the prisoners of wars who taught literacy to a certain number of Muslims. All these emphases and recommendations have urged Muslims to travel to gain knowledge. As a result, Muslims who traveled to other places and countries were practically the messengers of Islam there, which, in consequence, accelerated the spread of Islam.

Continuous interaction with the world During Islam's History 

The actual advances all over the world are the outcomes of the efforts that various nations and civilizations have made in the course of time, among which are the Islamic civilizations [6]. Muslims in different countries, like Spain and Italy, have always been in interaction with other people; therefore, they could transfer the Islamic civilization and culture to others and also receive from them. As an instance, in the battle of the Trench (Khandaq), Salman Farsi proposed to dig a trench around Medina.

This was a tested strategy in Persia, and Prophet Muhammad (PBUH&HP) accepted it. Many of the important Arabic resources and books were translated into European languages, some of which were later on taught and used as references in scientific centers in non-Muslim countries. The bonds between Muslims and Christians through marriage [i] and social relationships were of other means to expose non-Muslims to Islam [7]. All these factors have helped the quick spread of Islam.

From what has been discussed, we can see that the Islamic approach of making regulations under the form of confirmed rules, the encouragement to obtain knowledge and literacy, and cultural exchanges with the rest of the world played significant roles in attracting many savants and people to the religion of Islam.

It might have happened to you that when there is a ladder leaned against a wall and as you want to pass under it, someone calls you and says: “Do not pass under a ladder!” You might think it's crazy, or you might find it acceptable and even follow it. Which one is true? If you decide to follow Islam as your faith, should you follow those superstitious beliefs or ignore them all at once?

What Is Superstition?

Collins Concise English Dictionary defines superstition as an irrational belief usually founded upon ignorance or fear and characterized by obsessive reverence for omens, charms, etc. [1]. Superstitious beliefs are not limited to a particular faith or region; all nations and clans have their own beliefs, followed by their fears and ignorance. They are mostly routed in the past of a nation, transferred from generation to generation.

Does Islam Say Anything about Superstitions?

Islam defines superstition as all the words, manners and beliefs without a religious or logical base and backbone [2].

The Quran defines superstition as a burden put upon the human mind and soul by his/her own hands. It introduces Prophet Muhammad (PBUH&HP) to us as the last messenger of Allah, responsible to make things clear for his followers to see what to do and believe in, and what not to do and ignore [3]. 

"Those who follow the Messenger, the unlettered prophet, whom they find written in what they have of the Torah and the Gospel, who enjoins upon them what is right and forbids them what is wrong and makes lawful for them the good things and prohibits for them the evil and relieves them of their burden and the shackles which were upon them. So they who have believed in him honored him, supported him and followed the light which was sent down with him - it is those who will be successful.” (7:157)

Shackles are those beliefs human beings had or might have, which made them do things and stop doing some others with no definite reason or scientific study and research. It is the duty of Islam to guide people to accept everything they believe in with their hearts and minds sure of it, which requires research and reasoning. 

But What If I Still Want to Follow Superstitions in Which I Believe?

Well, there was a time when superstitions were limited to passing under a ladder or seeing a black cat. But now, superstitions are more woven in the lives of people. Reports have shown that a quarter of adults in the United States consider themselves to be so. American Youths are more superstitious than the elders, and 70 percent of them rely on luck charms for better academic results. According to some scientific research, this occurs because people think superstitions can relieve their anxieties, improve their performances and help them pay the extra costs of an adverse outcome, be it financial, mental, or whatsoever [4]. 

As you might also conclude, superstitions have not only been less common, but also they are becoming more frequent among young Americans. There are ways to overcome those beliefs which we are going to discuss in our next article. Still, aside from that, these words uncover one fact: when you follow superstitions and believe in them, they will take the lead in your life and the life of your children, family, friends, etc. One day you might come up with the fact that many of your friends' fears passing under a ladder, too.

The other outcome of following superstitious beliefs is a weaker mental belief in a superpower. Put simply, when you believe in superstitions, you see other powers, be it of Satan, natural elements, or any other thing, stronger and more effective than that of Allah. You might not mean or think that way, but being superstitious makes you so. 

One last important aftermath of this system of thinking is a feeble religious mind, one which is easily broken, misled, and gone far away from the straightway of truth. Superstitions weaken your faith, and then they weaken you. A weak person goes forward with a slow speed.

These are the least consequences of superstitious beliefs. You might think about the ways of overcoming these thoughts and getting rid of them which we will discuss later. 

So, Are you still afraid of passing under a ladder?
