Haritha b. Wahb reported Allah's Messenger (ﷺ) as saying
Give Sadaqa for a time is about to come when a person would walk with alms and the one whom it is to be given would say: Had you brought it yesterday, I would have accepted it. For the present I do not need it. (And the giver of Sadaqa) I would not find anyone to accept it.
Abu Musa reported Allah's Messenger (ﷺ) as saying
There would come a time for the people when a person would roam about with Sadaqa of gold, but he would find no one to accept it from him. And a man would be seen followed by forty women seeking refuge with him on account of the scarcity of males and abundance of females."
Abu Huraira reported Allah's Messenger (way peace be upon him) as saying
The Last Hour will not come before wealth becomes abundant and overflowing, so much so that a man takes Zakat out of his property and cannot find anyone to accept it from him and till the land of Arabia becomes meadows and rivers.
Abu Huraira reported Allah's Messenger (ﷺ) as saying
The Last Hour will not come till wealth is abundant and overflowing, so much so that the owner of the property will think as to who will accept Sadaqa from him, and a person would be called to accept Sadaqa and he would say: I do not need it.
Abu Huraira reported Allah's Messenaer (ﷺ) as saying
The earth will vomit long pieces of its liver like columns of gold and silver, and the murderer will come and say: It was for this that I committed murder. The breaker of family ties will come and say: It was for this that I broke the family ties; and the thief will come and say: It is for this that my hands were cut off. They will then leave it and will not take anything out of it.
