SALAAM AT THE TIME OF MEETING

It is related by Aboo Hurayrah radhiyallahu anhu that the Apostle of Allah sallallahu alayhi wasallam said,
"When anyone of you meets a Muslim brother, he should offer him salaam, and if a tree, wall or rock comes between them, (and they cannot see each other for sometime), then they come face to face again, he should offer him salaam once more."

Aboo Daawood

COMMENTARY:
If two Muslims meet and are separated after the salaam, even for a brief moment, and then they meet again, they should convey salaam a second time. One can learn from this how important it is to offer salaam in the teachings of the Prophet sallallahu alayhi wasallam and the Sharee'ah.
