The Hanifiyyah Or The Religion of Abraham
Hanifiyyah is to devote sincerely all acts of worship to Allah alone. This is what Allah has enjoined on all people, and for this reason He has created them. In the Qur’an we read::
“I have created the jinn and the humans only that they should worship Me.” [Q 51:56]
The meaning of “to worship Me” is to profess Allah’s Oneness, believing that Allah is the One Who commands and Who imposes prohibitions.
The greatest thing that Allah has enjoined is at-Tawheed, i.e. monotheism. Monotheism is declaring Allah to be the only god Who deserves to be worshipped in truth, and confirming the attributes with which He has qualified Himself and those attributed to Him by His Messenger [PBUH]. Tawheed is also believing that Allah far removed from every imperfection or resembling His creatures.
The greatest thing that Allah has forbidden is Shirk or polytheism. Polytheism is worshipping other gods beside Allah, and setting up rivals to Allah. In the Qur’an we read:
“So do not set equals to Allah while you know (there is none equal to Him).” [Q 2:22]
