From explanation By Shikh BenOthaimieen The first thing that one should know and clearly understand about Islam is what the word "Islam" itself means.

Islam is an Arabic word the root of which is Silm and Salam. It means among others: peace, greeting, salutation, obedience, loyalty, allegiance, and submission to the will of the Creator of the Universe. Islam is the Deen, (religion) which Allah (the Creator of the whole Universe) has sent and perfected for His creation.

Islam is the religion which was given to Adam, the first man and the first prophet of Allah, and it was the religion of all the prophets sent by Allah to mankind.

The name of God’s religion lslam was not decided upon by later generations of man. It was chosen by Allah Himself and clearly mentioned in His final revelation to man.

In the final book of divine revelation, the Qur’aan, Allah states the following: ( اليوم أكملت لكم دينكم و أتممت عليكم نعمتى و رضيت لكم الإسلام دينا) ( المائدة ، 30) This day6, I have perfected your religion for you , and completed my favour upon you, and have chosen for you Al-Islam as your Deen. ( Qura’an :5:30).

The Deen of Islam embraces all of the human welfare that is comprised in the previous religions ; it is distinguished from all the religions in it’s suitability for all times , places , and nations, Allah تعالى addresses His Messenger Mohammed saying : ( و أنزلنا إليك الكتاب بالحق مصدقا لما بين يديه من الكتاب و مهيمنا عليه ) ( المائدة ،48) And We have sent down to you ( O Mohammed ) the Book ( this Qura’an) in truth , confirming the scripture that came before it and Muhayminan ( trustworthy in highness and witness) over it ( Old Scripture) . ( Qura’an 5:48)

The suitability of the Deen means that adhering to Islam does not contradict the welfare of the Ummah (Muslim community at large) in any place or in any time. Indeed it is its betterment.

This does not mean, however, that the Deen is subjugate to every time , place and Ummah as some people like it to be. Allaah تعالى3 also says: ( و ما أرسلنا من قبلك من رسول إلا نوحى إليه أنه لا إله إلا أنا فأعبدون) And we did not send any Messenger before you (O Mohammed) but We inspired him (saying(: Lailaha illa Ana {none has the right to be worshipped but I (Allah)},so worship Me (alone and no one else).( Qur’aan 21:25(4 The Deen of Islam is Aqeedah ( Creed) and Sharee’ah ( Legislation ) and it is perfect in both .

Islaam commands: The Tawheed and forbids Shirk ( setting associate with Allaah). Truthfulness, and forbids lying. Justice, and forbids oppression. Trustworthiness, and forbids treachery. Faithfulness, and forbids betrayal To be good and dutiful to one’s parents, and forbids being disrespectful to them.

Keep ties with relatives of kinship, and forbids severing ties with them. To have good relation to one’s neighborhood, and forbids all forms of ill-treatment to the neighbors.

Generally speaking , Islam commands all noble morals , and forbids all ill and despicable manners; it also commands righteousness and forbids wrong.

Allaaah تعالى says: ( إن الله يأمر بالعدل و الإحسان و إيتاء ذى القربى و ينهى عن الفحشاء و المنكر و البغى يعظكم لعلكم تذكرون) ( النحل ، 90) Verily, Allaah enjoins Al-‘Adel (i.e justice and worshipping none but Allaah) and Al-Ihsan12, and giving help to kith and kin13 , and forbids Al-Fahsha14 , Al-Mankar15 , and Al-Baghy16 .(Qura’an 16:90)

6 This Ayah ( Verse) was sent down during Hajatul Wadaa’ ( Farewell Pilgrimage) of the prophet , on the day of Arafah which was a Friday.

12 Al-Ihsan: In This Aayah it means to patient in performing one’s duties to Allaah’s sake and in accordance with the Sunah of the prophet Mohammed 13 Degree of Kinship : First of all , your parents then your paternal uncles and aunts ( from the mother’s side) , then other relative.

14 Al-Fahshaa: All evil deeds eg; illegal sexual intercourse , disobedience to parents , to tell lies., to steal.

15 Al-Munkar : All that is prohibited by Islaamic law: Polytheists , disbelief , and every kind of evil deeds.
