Are three `Umrahs Equivalent to Hajj?

Making `umrah (lesser pilgrimage) during Ramadan three times, according to many scholars, is rewarded like the Hajj. However, it does not eliminate the obligation of Hajj. You will given the reward (fadilat) of Hajj without fulfilling its obligation. Even if you did thousands of `umrah in Ramadan it would not eliminate the requirement for making the Hajj. Unless you do the actual Hajj during its season with its required rites, you will not be considered to have completed this requirement of the faith. Nowhere is it mentioned in Quran or hadith that this, the 5th pillar of Islam can be substituted by `umrah during Ramadan. Since you were able to do the `umrah, it means you are able to do Hajj, and this is what is advised.
