Al-’Ehn or
Al-Yaseerah Well where it is said our Blessed Prophet
SallAllahu alaihi wasallam made Wudhu. It
is enclosed in a fenced archeaological site.(Al-Miskeenah)
According to Hadith, he enquired about its name
and was told it was called 'Aseerah (difficult, or hard). He
replied that its name was not 'Aseerah but Yaseerah (easy or
soft) and adding his spittle in it, prayed for its blessing. -
