A man paid in advance for a palm-tree. It did not bear fruit that year. They brought their case for decision to the Prophet (ﷺ). He said: for which do you make his property lawful? He then said: Do not pay in advance for a palm-tree till they (the fruits) were clearly in good condition.
I heard the Messenger of Allah (ﷺ) say: This religion will continue to be strong till the time of twelve caliphs. The people then uttered: Allah is more great and uproared. He then silently a word which I could not understand. So I said to my father: What did he say, father ? He said: All of them will belong to Quraish.
