In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
وَلَقَدۡ كَرَّمۡنَا بَنِىٓ ءَادَمَ وَحَمَلۡنَـٰهُمۡ فِى ٱلۡبَرِّ وَٱلۡبَحۡرِ وَرَزَقۡنَـٰهُم مِّنَ ٱلطَّيِّبَـٰتِ وَفَضَّلۡنَـٰهُمۡ عَلَىٰ ڪَثِيرٍ۬ مِّمَّنۡ خَلَقۡنَا تَفۡضِيلاً۬
And indeed We have honoured the Children of Adam, and We have carried them on land and sea, and have provided them with At-Taiyibat (lawful good things), and have preferred them above many of those whom We have created with a marked preference. [Surah Al-Israa. Aayah 70]
I praise and thank Allaah, who knows everything about what He has created and He is the Most Kind and Courteous (to His slaves), All-Aware (of everything). He is praised with all good – praised for His commands, prohibitions, divine legislation and what He has created. It is He who guided humankind and commanded them with what will lead them to perfection and wellbeing in their worldly life and afterlife. He alone is deserving of abundant (unlimited) praise just as He bestowed on us abundant (innumerable) blessings. I bear witness that none has the right to be worshipped except Allaah alone and He has no partner, and I bear witness that Muhammad is Allaah’s slave and Messenger. May Allaah’s peace and blessings be upon him, his family and companions. To proceed:
O my brothers! Indeed, these are blessed hours when one learns something about his religion which he did not know or he (recalls) and consolidate what he forgot after a period of time – affairs he forgot unintentionally due to the many affairs and being preoccupied with other things.
There is no doubt that no other divine legislation came to the people that is more perfect than the Islamic legislation. Allaah gave every Prophet a law and a path, and He made Muhammad’s law a complete and perfect law, perfectly suitable until the day of judgement- suitable for every era and place. [Ref 1] [NB: Must refer to footnotes of this reference at the end of the article]
Muhammad’s law solves every problem, preserves every obligation that should be fulfilled, raises every affair that honours the human being, honours the Muslim and raises him because he carries the message of pure Islamic monotheism. So due to this, it is obligated on everyone to be acquainted with the virtues of this divine legislation, know its rulings, its goals and underlying wisdoms, the obligations it has laid down and what inspires them to preserve and call to it, and that they do not pay attention to any caller to misguidance – those who want to hinder humankind from the truth through different terms and slogans. [i.e. Those who are eager to ridicule and make it look repugnant, in order to make people flee from it. See Tafseer as-Sadi. Surah Ibraaheem. Aayaat 1-3]
We praise and thank Allaah for including us amongst those who have accepted and submitted to this divine legislation- those who learn and strive to follow the behaviour of Allaah’s Messenger [peace and blessings of Allaah upon him].
Allaah created the heavens and the earth for the fulfilment of two obligations – His Rights and the rights of His servants. Every Messenger and the divine scriptures were sent to explain these two obligations- 1: Worship Allaah alone, disbelieve in all the rivals and false gods that are associated with Him as partners, and 2: Obey His Messenger in that particular era and place. Allaah revealed His Books and sent His Messengers to establish these two obligations.
Allaah [The Exalted] said:
لَقَدۡ أَرۡسَلۡنَا رُسُلَنَا بِٱلۡبَيِّنَـٰتِ وَأَنزَلۡنَا مَعَهُمُ ٱلۡكِتَـٰبَ وَٱلۡمِيزَانَ لِيَقُومَ ٱلنَّاسُ بِٱلۡقِسۡطِ
Indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance (justice) that mankind may keep up justice. [Surah Al-Hadeed. Aayah 25]
وَلَقَدۡ بَعَثۡنَا فِى ڪُلِّ أُمَّةٍ۬ رَّسُولاً أَنِ ٱعۡبُدُواْ ٱللَّهَ وَٱجۡتَنِبُواْ ٱلطَّـٰغُوتَ
And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): “Worship Allah (Alone), and avoid (or keep away from) Taghut (all false deities, etc. i.e. do not worship Taghut besides Allah).” [ Surah An-Nahl. Aayah 36]
And because of this, the Messenger [peace and blessings of Allaah be upon him] said: “O Mu’adh, do you know what is the right of Allah upon His servants?” I said, “Allah and his messenger know best.” The Prophet said, “To worship Him alone and to associate none in worship with Him. And do you know what is their right upon Him?” I said, “Allah and his messenger know best.” The Prophet said, “Not to punish them if they do so.” [Bukhaari 6938]
The obligations which all the divine laws brought in general and the Islamic legislation in specific are: To fulfil Allaah’s Right, fulfil the rights of the creation and the rights of the human being. There is no doubt that this will be made very clear when you contemplate on Allaah’s Book and the Sunnah of His Messenger.

Ref 1: The implementation of Sharee’ah Law is the responsibility of Muslim governments and not the insurgents, such as ISIS and their ilk. Likewise, the call to Islaam does not begin with the call to establish an Islamic State nor the implementation of Sharee’ah Law on the people, rather it begins with the call to pure Islamic Monotheism. See here the Methodology of the Prophets in calling to the path of Allaah:
Rectification of Society – By Imaam Abdul Azeez Bin Baaz [may Allaah have mercy upon him]
ISIS have NOT established the Khilaafah! [i.e. The Islamic State]- By Shaikh Abu Khadeejah [may Allaah preserve him]
And even when Muslim rulers are oppressive, we do not initiate rebel against them. See here: The Tyranny Of The Rulers, A Reason For Rebellion?
Sharee’ah In The West
Shaikh Abdul Waahid Abu Khadeejah [may Allaah preserve him] stated:
Although Muslims in Britain are subject to British law and the British legal system, Sharī’ah tribunals are allowed in certain areas as an alternative way of resolving disputes. These are aimed at resolving commercial, civil and matrimonial disputes to the satisfaction of both sides.

Also, a Muslim is obligated to fulfil his obligations and refrain from treachery whilst living with non-Muslims. See here: Living With Non-Muslims In The West: With Fine Conduct
