In order to get the reward for a complete hajj and umrah, is it a condition to sit until sunrise in the same prayer area where I prayed fajr?

In the name of Allah, all praise is due to Allah, and may the peace and blessings be upon the Messenger of Allah. It was narrated in an authentic hadith that “whoever prays fajr in congregation and then sits and remembers Allah until sunrise, he will have the reward equal to a Hajj and Umrah, complete, complete, complete.” The apparent meaning of the hadith is that he sits in the same prayer area and this is the default situation, although there are no limits upon the blessings of Allah to reward him with this even if he moves from his prayer area if there is a need to do so. And Allah is the Highest and All-Knowing.
