What was the general guideline given by Prophet Muhammad (saw) regarding the sale of fruits?
 p>     Narrated Anas bin Malik:                          Allah's Apostle forbade the sale of fruits till they are almost ripe.      He was asked what is meant by 'are almost ripe.' He replied, "Till      they become red." Allah's Apostle further said, "If Allah spoiled the      fruits, what right would one have to take the money of one's brother      (i.e. other people)?"
