A person left the mosque and crossed the mosque wall, then returned to the mosque; is he required to perform the greeting of the mosque?

The questioner : In this case, we say: if, for example, a person left the mosque—meaning he crossed the sanctity of the mosque wall for a short time, perhaps to buy medicine—and then returned to the mosque; is he required to perform the two rak'ahs of the greeting of the mosque here?

The Shaykh : Was he sitting in the mosque?

The questioner : Yes, he was sitting.

The Shaykh : Then he left?

The questioner : He left; he had crossed its sanctity a little.

The Shaykh : Then it must have been a short time or a long time; as long as he left the mosque, the greeting is required before sitting.
