their benefits and the straight path and keeps them away from the way of Hellfire and destruction.
Muslims have obligations related to their holding fast to their religion as Allah ordained. Allah has created people to worship Him and sent messengers to inform them of this.
And I (Allâh) created not the jinn and mankind except that they should worship Me (Alone).
O mankind! Worship your Lord (Allâh), Who created you and those who were before you so that you may become AlMuttaqûn (the pious See V.2:2).
Worship Allâh and join none with Him (in worship)
And they were commanded not, but that they should worship Allâh, and worship none but Him Alone (abstaining from ascribing partners to Him), and perform AsSalât (IqâmatasSalât) and give Zakât, and that is the right religion.
And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): "Worship Allâh (Alone), and avoid (or keep away from) Tâghût (all false deities i.e. do not worship Tâghût besides Allâh)."
And We did not send any Messenger before you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) but We revealed to him (saying): Lâ ilâha illa Ana [none has the right to be worshipped but I (Allâh)], so worship Me (Alone and none else)."
Allah (Exalted be He) sent His Messenger Muhammad (peace be upon him) like all the messengers before him to call people to this `Ibadah and to this Din (religion) of Islam. Allah sent Muhammad to both mankind and jinn as a mercy
And We have sent you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ): not but as a mercy for the 'Alamîn (mankind, jinn and all that exists).
and guide to salvation, teaching all that benefits people and secures their salvation and happiness in this life and the Hereafter. Allah (Exalted be He) made him the seal of the prophets, no other prophet or messenger shall ever come after him. Whoever claims to be a prophet after him is a liar and Kafir (disbeliever) according to the Ijma` (consensus of scholars).
Whoever claims prophethood or inspiration, such as AlQadayaniyyah, is Kafir who has gone astray and leads people astray and is a Murtad (apostate) who comes out of the fold of Islam, if he claims Islam, Muhammad (peace be upon him) is the seal of all prophets and messengers.
Muhammad (ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) is not the father of any of your men, but he is the Messenger of Allâh and the last (end) of the Prophets.
There are many Sahih (authentic) Hadith reported by the Prophet (peace be upon him) that prove that he is the Last Prophet. It is obligatory upon both mankind and Jinn to follow him and hold fast to his Din and try to comprehend it till death. They must seek understanding this `Ibadah for which they were created and should realize it by evidences from the Book and Sunnah. They are created to worship Allah and this `Ibadah is to be interpreted by what revealed by Allah and His Messenger.
Allah (Exalted be He) interpreted it in the EverGlorious Qur'an as did His Messenger (peace be upon him). The essence of `Ibadah is Tawhid (belief in the Oneness of Allah/ monotheism) and devotion.
And they were commanded not, but that they should worship Allâh, and worship none but Him Alone (abstaining from ascribing partners to Him)
This is the basis of `Ibadah to believe in Allah (Exalted be He) and worship him Alone.
And We did not send any Messenger before you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) but We revealed to him (saying): Lâ ilâha illa Ana [none has the right to be worshipped but I (Allâh)], so worship Me (Alone and none else)."
All divine books were revealed by Allah (Glorified and Exalted be He) to clarify the `Ibadah.
(This is) a Book, the Verses whereof are perfected (in every sphere of knowledge), and then explained in detail from One (Allâh), Who is AllWise, WellAcquainted (with all things).
