I heard Messenger of Allah ﷺ saying, "Give in charity because there will come a time on the people when a person will go out with his alms from place to place but will not find anybody to accept it."
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ تَصَدَّقُوا فَسَيَأْتِي عَلَى النَّاسِ زَمَانٌ يَمْشِي الرَّجُلُ بِصَدَقَتِهِ فَلاَ يَجِدُ مَنْ يَقْبَلُهَا قَالَ مُسَدَّدٌ حَارِثَةُ أَخُو عُبَيْدِ اللَّهِ بْنِ عُمَرَ لأُمِّهِ قَالَهُ أَبُو عَبْدِ اللَّهِ
