History of Kaabah and Islam

Kaaba is considered the holiest place on the Earth. There are several verses in the Quran about the revered Kaaba, where it is described as the first house of worship for mankind.

It is where Muslims go to perform Umrah and Hajj 

Hajj is obligatory upon every Muslim if they're financially, physically capable.

Umrah is voluntary.

Kaaba is situated in the blessed city of Makkah where Prophet SAWS was born.

before there were idols in Kaaba since the bad idolaters were pagans, mushriks, associating partners with Allah SWT. Prophet Muhammad SAWS received the revelation from Allah and completed Islam by the miracle of the Quran, book for mankind, destroying pre–Islamic Arabia evil, female killing, giving rights to the poor and slaves, manners to neighbours and how-to walk-in life for every matter from waking up, sleeping, walking, communication, law, marriage, eating, trading, business, etc.

Prophet Muhammad SAWS entered Makkah after 10-11 years of persecution and removed all the idols from the Kaabah, and Allah granted victory to the Muslims as decreed by Him, now there are more than 2 billion adherents alive in the Earth right now.

Preaching only one message

There is no god but Allah SWT

and Muhammad SAWS Is His messenger

 Kaaba was originally a sacred place where angels would worship God in the days before man was created. Later, Adam (yes, that Adam, partner to Eve) built a shrine to God on that spot, but it too was destroyed by the ravages of time. When Abraham came along, he and his son Ismail rebuilt the Kaaba on the foundations of Adam’s earlier shrine as a place of worship of the one God.

Kaaba has no power, in of itself. It is a house of worship, and house of Allah SWT.

Power is with Allah SWT only.

No building, No Human, No Animal has the power unless Allah grants it to the entity.

Umrah is a short pilgrimage that you can do at any time,Muslims journey around the Ka’aba seven times in an anticlockwise direction. whereas Hajj takes longer, involves more rituals, and can only be performed at a specific time of year. They may both be important, spiritual journeys that bring you closer to Allah (SWT), but they're not the same. 

Islam was always there, always is, and will be. It has not "arrived", but it was completed after Allah SWT revealed His Book Quran for the entire mankind, till the day of judgement.

Quran is the confirmation of previous scriptures (Torah, Injeel), till this day Quran corrects the contradictions found in Bible and Torah (as they have not been preserved by Allah)
