If a worshipper intends to perform a voluntary prayer after the obligatory prayer, it is recommended that he change his location; what is the wisdom behind this?

The questioner : Regarding the individual, when he performs the obligatory prayer, the recommended practice is for him to change his location; what is the wisdom behind this?

The Shaykh : He came back and greeted you. [Everyone laughs!]
First, I say—as is my custom—this is the recommended practice; this is how the hadith came in "Sunan Abu Dawud" regarding changing the location of the voluntary prayer from the obligatory one. And in "Sahih Muslim," there is another hadith concerning the Friday prayer: that if he prays the Friday prayer, let him go out or speak, and not connect the voluntary prayer to the obligatory one. As for the wisdom, as you ask, some mention—and Allah knows best—that it is to increase the witnesses on the Day of Resurrection, to increase the witnesses for him with good on the Day of Resurrection. So whenever he prays in a place, that place becomes a witness for him; because he prayed in it for Allah (Mighty and Majestic) two rak'ahs or more. This is what has been said, and Allah knows best; it may be correct, and it may not be.
