I heard the Prophet ﷺ saying, "O people! Give in charity as a time will come upon you when a person will wander about with his object of charity and will not find anybody to accept it, and one (who will be requested to take it) will say, "If you had brought it yesterday, would have taken it, but today I am not in need of it."  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ تَصَدَّقُوا فَإِنَّهُ يَأْتِي عَلَيْكُمْ زَمَانٌ يَمْشِي الرَّجُلُ بِصَدَقَتِهِ فَلاَ يَجِدُ مَنْ يَقْبَلُهَا يَقُولُ الرَّجُلُ لَوْ جِئْتَ بِهَا بِالأَمْسِ لَقَبِلْتُهَا فَأَمَّا الْيَوْمَ فَلاَ حَاجَةَ لِي بِهَا  

Thy Prophet ﷺ said, "A time will come upon the people when a person will wander about with gold as Zakat and will not find anybody to accept it, and one man will be seen followed by forty women to be their guardian because of scarcity of men and great number of women. "  

عَنِ النَّبِيِّ ﷺ قَالَ لَيَأْتِيَنَّ عَلَى النَّاسِ زَمَانٌ يَطُوفُ الرَّجُلُ فِيهِ بِالصَّدَقَةِ مِنَ الذَّهَبِ ثُمَّ لاَ يَجِدُ أَحَدًا يَأْخُذُهَا مِنْهُ وَيُرَى الرَّجُلُ الْوَاحِدُ يَتْبَعُهُ أَرْبَعُونَ امْرَأَةً يَلُذْنَ بِهِ مِنْ قِلَّةِ الرِّجَالِ وَكَثْرَةِ النِّسَاءِ  

The Prophet ﷺ said, "The Hour (Day of Judgment) will not be established till your wealth increases so much so that one will be worried, for no one will accept his Zakat and the person to whom he will give it will reply, 'I am not in need of it.' "  

قَالَ النَّبِيُّ ﷺ لاَ تَقُومُ السَّاعَةُ حَتَّى يَكْثُرَ فِيكُمُ الْمَالُ فَيَفِيضَ حَتَّى يُهِمَّ رَبَّ الْمَالِ مَنْ يَقْبَلُ صَدَقَتَهُ وَحَتَّى يَعْرِضَهُ فَيَقُولَ الَّذِي يَعْرِضُهُ عَلَيْهِ لاَ أَرَبَ لِي
