To practise charity before such time when nobody would accept it

Narrated Haritha bin Wahab :

I heard the Prophet 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 to-day I am not in need of it."

حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا مَعْبَدُ بْنُ خَالِدٍ، قَالَ سَمِعْتُ حَارِثَةَ بْنَ وَهْبٍ، قَالَ 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 ".

Narrated Abu Huraira:

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.' "

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، حَدَّثَنَا أَبُو الزِّنَادِ، عَنْ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ 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 ".

Narrated 'Adi bin Hatim:

While I was sitting with Allah's Apostle ﷺ two person came to him;
one of them complained about his poverty and the other complained about the prevalence of robberies. Allah's Apostle ﷺ said, "As regards stealing and robberies, there will shortly come a time when a caravan will go to Mecca (from Medina) without any guard. And regarding poverty, The Hour (Day of Judgment) will not be established till one of you wanders about with his object of charity and will not find anybody to accept it And (no doubt) each one of you will stand in front of Allah and there will be neither a curtain nor an interpreter between him and Allah, and Allah will ask him, 'Did not I give you wealth?' He will reply in the affirmative. Allah will further ask, 'Didn't I send a messenger to you?' And again that person will reply in the affirmative Then he will look to his right and he will see nothing but Hell-fire, and then he will look to his left and will see nothing but Hell-fire. And so, any (each one) of you should save himself from the fire even by giving half of a date-fruit (in charity). And if you do not find a half date-fruit, then (you can do it through saying) a good pleasant word (to your brethren). (See Hadith No. 793 Vol. 4).

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو عَاصِمٍ النَّبِيلُ، أَخْبَرَنَا سَعْدَانُ بْنُ بِشْرٍ، حَدَّثَنَا أَبُو مُجَاهِدٍ، حَدَّثَنَا مُحِلُّ بْنُ خَلِيفَةَ الطَّائِيُّ، قَالَ سَمِعْتُ عَدِيَّ بْنَ حَاتِمٍ ـ رضى الله عنه ـ يَقُولُ كُنْتُ عِنْدَ رَسُولِ اللَّهِ ﷺ فَجَاءَهُ رَجُلاَنِ أَحَدُهُمَا يَشْكُو الْعَيْلَةَ، وَالآخَرُ يَشْكُو قَطْعَ السَّبِيلِ، فَقَالَ رَسُولُ اللَّهِ ﷺ " أَمَّا قَطْعُ السَّبِيلِ فَإِنَّهُ لاَ يَأْتِي عَلَيْكَ إِلاَّ قَلِيلٌ حَتَّى تَخْرُجَ الْعِيرُ إِلَى مَكَّةَ بِغَيْرِ خَفِيرٍ، وَأَمَّا الْعَيْلَةُ فَإِنَّ السَّاعَةَ لاَ تَقُومُ حَتَّى يَطُوفَ أَحَدُكُمْ بِصَدَقَتِهِ لاَ يَجِدُ مَنْ يَقْبَلُهَا مِنْهُ، ثُمَّ لَيَقِفَنَّ أَحَدُكُمْ بَيْنَ يَدَىِ اللَّهِ لَيْسَ بَيْنَهُ وَبَيْنَهُ حِجَابٌ وَلاَ تُرْجُمَانٌ يُتَرْجِمُ لَهُ، ثُمَّ لَيَقُولَنَّ لَهُ أَلَمْ أُوتِكَ مَالاً فَلَيَقُولَنَّ بَلَى. ثُمَّ لَيَقُولَنَّ أَلَمْ أُرْسِلْ إِلَيْكَ رَسُولاً فَلَيَقُولَنَّ بَلَى. فَيَنْظُرُ عَنْ يَمِينِهِ فَلاَ يَرَى إِلاَّ النَّارَ، ثُمَّ يَنْظُرُ عَنْ شِمَالِهِ فَلاَ يَرَى إِلاَّ النَّارَ، فَلْيَتَّقِيَنَّ أَحَدُكُمُ النَّارَ وَلَوْ بِشِقِّ تَمْرَةٍ، فَإِنْ لَمْ يَجِدْ فَبِكَلِمَةٍ طَيِّبَةٍ ".
