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.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، نُمَيْرٍ قَالاَ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا شُعْبَةُ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، - وَاللَّفْظُ لَهُ - حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ مَعْبَدِ بْنِ خَالِدٍ، قَالَ سَمِعْتُ حَارِثَةَ بْنَ وَهْبٍ، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " تَصَدَّقُوا فَيُوشِكُ الرَّجُلُ يَمْشِي بِصَدَقَتِهِ فَيَقُولُ الَّذِي أُعْطِيَهَا لَوْ جِئْتَنَا بِهَا بِالأَمْسِ قَبِلْتُهَا فَأَمَّا الآنَ فَلاَ حَاجَةَ لِي بِهَا . فَلاَ يَجِدُ مَنْ يَقْبَلُهَا " .
