ignorant of it. Hence, they commit acts that contradict it. Praise be to Allah, the other two categories are very clear. However, many people become dubious about the Oneness of Allah's Worship due to the great deal of doubts that enemies of Allah cast on people. Nevertheless, it is also clear for those whom Allah endowed with insight, because they are baseless false claims.
The truth is unquestionably obvious; it is obligatory to dedicate acts of worship to Allah Alone, and nobody else. Allah (Glorified and Exalted be He) says: So, call you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ and the believers) upon (or invoke) Allâh making (your) worship pure for Him (Alone) (by worshipping none but Him and by doing religious deeds sincerely for Allâh's sake only and not to show off and not to set up rivals with Him in worship), however much the disbelievers (in the Oneness of Allâh) may hate (it).
He (may He be Praised and Glorified) says: so invoke not anyone along with Allâh. He (may He be Praised) also says: "And invoke not besides Allâh, any such that will neither profit you nor harm you, but if (in case) you did so, you shall certainly be one of the Zâlimûn (polytheists and wrongdoers)." Allah (Exalted be He) says: Such is Allâh, your Lord; His is the kingdom. And those, whom you invoke or call upon instead of Him, own not even a Qitmîr (the thin membrane over the datestone).
If you invoke (or call upon) them, they hear not your call; and if (in case) they were to hear, they could not grant it (your request) to you. And on the Day of Resurrection, they will disown your worshipping them. And none can inform you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) like Him Who is the AllKnower (of everything). He (may He be Praised) says: And whoever invokes (or worships), besides Allâh, any other ilâh (god), of whom he has no proof; then his reckoning is only with his Lord. Surely! A lKâfirûn (the disbelievers in Allâh and in the Oneness of Allâh, polytheists, pagans, idolaters) will not be successful.
There are numerous Ayahs stressing the obligation of being sincere to Allah Alone in worship and that dedicating worship to anyone other than Allah is Shirk and Kufr. Also, if anyone believes that a human being or an inanimate object may be worshipped, he will be a disbeliever even if he himself does not worship it. Likewise, if he believes that an idol, Gabriel, the Prophet Muhammad (peace be upon him), Shaykh, `Abdul Qadir AlJilany, AlBadawy , AlHusayn or `Aly ibn Abu Talib if he believes that
any of them is worthy of worship or that there is no harm in supplicating or seeking relief from any of them along with Allah, he will be disbeliever even if he does not commit any sin. If a person believes that they know the Ghayb (the Unseen) or dispose the affairs of the universe, he will be a disbeliever according to all scholars. The case becomes more serious if he supplicates them apart from Allah or seeks relief from them or makes a vow for them, he will be committing major Shirk (associating others with Allah in His Divinity or worship).
The same ruling applies to a person who prostrates, offers Salah (prayer), or observes Sawm (fasting) for their sake. We implore Allah to grant us safety from that.
