Praise be to Allah, the Lord of the Worlds, and peace be upon our Prophet Muhammad and upon all his Family and Companions.
We previously published a brief work entitled "Muharamaat: Prohibitions that are taken too lightly", which discussed some of the various offences against Sharee’ah which may involve shirk and major and minor sins. Evidence for these things being prohibited was quoted from the Qur'an and Sunnah, and real-life situations were described in order to explain clearly the different ways in which people may fall into committing sin.
There are many things that have been prohibited in the Qur'an and Sunnah, and it is very important for the Muslim to know about them so that he can keep away from them and thus avoid earning the wrath and anger of Allah or bringing about his own doom in this world and the next. So I thought of compiling this list of prohibited things, in accordance with the hadeeth of the Prophet (peace and blessings of Allah be upon him): "Religion is sincere advice (al-deen al-naseehah)," and in the hope that it will be of benefit both to myself and to my Muslim brothers. So I have compiled what information I could from the Qur'an and from the hadeeth classed as saheeh by the scholars who specialize in this field (relying mostly on the reports classed as saheeh by al-‘Allaamah Muhammad Naasir al-Deen al-Albaani in his books). Topics are grouped according to the classifications used in fiqh (Islamic jurisprudence). I have not quoted every hadeeth in full, only the relevant parts. In most cases the reports include words which clearly indicate prohibition (such as "Do not…"), and I have explained the reason for the prohibition in some cases. I ask Allah to help us to avoid sin and wrongdoing wherever it exists, visible or hidden, and to accept our repentance.
Praise be to Allah, Lord of the Worlds.
List of prohibitions mentioned in the Qur'an and Sunnah
Allaah and His Messenger have prohibited many things, avoiding which brings great benefits and protects us from many kinds of evil and harm. These prohibitions include both things which are haraam (forbidden) and things which are makrooh (disliked, discouraged). The Muslim should avoid these things, because the Prophet (peace and blessings of Allah be upon him) told us: "What I have forbidden you to do, avoid." The committed Muslim is keen to avoid all things that have been prohibited, whether they are classed as haraam or makrooh. He does not act like the weak of faith, who do not care if they do things that are makrooh, even though taking such matters lightly leads to committing haraam deeds, as the makrooh deeds effectively form a barrier around haraam actions. Moreover, the person who avoids makrooh deeds will be rewarded for this, if he avoids them for the sake of Allah. On this basis, we make no distinction here between makrooh and haraam, because making this distinction requires a great deal of knowledge, but most of what follows describes actions that are haraam rather than makrooh. There now follows a list of things that are prohibited in Islam.

It is forbidden to eat game caught by an untrained dog, or where it has been caught by a number of dogs, such that it is impossible to tell which dog caught it.

impossible, namely to tie two grains of barley together.
