Ok I have to mention something related to 5 pillars of Islam and the general 'awareness' levels regarding them. Unfortunately... we are kept 'illiterate' when it comes to religion.
You must have definitely heard about the story that Prophet Muhammad when on his ascension to heaven.. met various Prophets and finally the number of prayers was set at 5. Right? Wrong actually.
The Five pillars were not given to Prophet Muhammad. They were all given to Prophet Abraham.
2:128 - Our Lord! And make us submissive unto Thee and of our seed a nation submissive unto Thee, and show us our ways of worship, and relent toward us. Lo! Thou, only Thou, art the Relenting, the Merciful.
People did the rites before Prophet Muhammad.
2:183 - O ye who believe! Fasting is prescribed for you, even as it was prescribed for those before you, that ye may ward off (evil)
Prophet Muhammad was told to follow 'religion of Abraham'...
22:78 - And strive for Allah with the endeavour which is His right. He hath chosen you and hath not laid upon you in religion any hardship; the faith of your father Abraham (is yours). He hath named you Muslims...
The tribe of Quraish was the keeper of Qibla. Remember Abraha? the one who tried to make his own Qibla some 50 years before the birth of Prophet? and for which 'Sura Feel' was revealed? This indicates that people used to observe Hajj before Prophet Muhammad was born.
