Essence of 'Ibadah (worship) for which Allah created Jinn and Mankind
This is a message from Abdul Aziz Bin Abdullah Ibn Baz to every Muslim who may receive it. May Allah show us the way of His faithful servants and keep us away from the way of those on whom the Wrath of Allah is upon and those who are astray, Amen. Assalamu 'alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you!) The most important obligation of the Mukallaf (person meeting the conditions to be held legally accountable for their actions) is to worship Allah (may He be Praised), the Lord of the heaven and earth and the Lord of the Great Throne. Allah (may He be praised) says in His Glorious Book,
Indeed your Lord is Allâh, Who created the heavens and the earth in Six Days, and then He rose over (Istawâ) the Throne (really in a manner that suits His Majesty). He brings the night as a cover over the day, seeking it rapidly, and (He created) the sun, the moon, the stars subjected to His Command. Surely, His is the Creation and Commandment. Blessed is Allâh, the Lord of the 'Alamîn (mankind, jinn and all that exists)!
Invoke your Lord with humility and in secret. He likes not the aggressors.
And do not do mischief on the earth, after it has been set in order, and invoke Him with fear and hope. Surely, Allâh's Mercy is (ever) near unto the gooddoers.
Allah informs us in His book that He created jinn and mankind in order to worship Him. Allah (Glorified be He) says, And I (Allâh) created not the jinn and mankind except that they should worship Me (Alone). This 'Ibadah (worship) for which Allah has created Jinn and Humanity means to believe in the Oneness of Allah and devote all forms of worship to Him Alone. These forms of 'Ibadah include, Salah (Prayer), Sawm (Fasting), Zakah (obligatory charity), Hajj (pilgrimage to Makkah), Sujud (prostration), Tawaf (circumambulation around the Ka'bah), slaughtering sacrifices, making vows, fearing, hoping, seeking help and protection and all kinds of Du'a' (supplication) as well as the adherence to what is stated in His Glorious book and the Sunnah of His honest Messenger (peace be upon him) concerning the commandments and prohibitions of the Shari'ah (Islamic law). Allah sent all Messengers and revealed the Books in order to call and show people how to worship Him in detail and
