What did the Prophet Muhammad (saw) say when asked which tree he would allow the camel to graze in a valley with one that has been partially eaten and one that has not?
 Narrated `Aisha:                     I said, "O Allah's Apostle! Suppose you landed in a valley where there is a tree of which something has been eaten and then you found trees of which nothing has been eaten, of which tree would you let your camel graze?" He said, "(I will let my camel graze) of the one of which nothing has been eaten before." (The sub-narrator added: `Aisha meant that Allah's Apostle had not married a virgin besides herself .)
