A man asked the Messenger of Allah ﷺ: Messenger of Allah, which sadaqah (charity) is the best ? He replied: (The best sadaqah is) that you give something as sadaqah (charity) when you are healthy, greedy, expect survival and fear poverty, and not that you postpone it until your death. and then you say: For so-and-so is such-and-such, and for so-and-so is such-and-such, while it was already for so-and-so.  

رَجُلٌ لِلنَّبِيِّ ﷺ يَا رَسُولَ اللَّهِ أَىُّ الصَّدَقَةِ أَفْضَلُ قَالَ أَنْ تَصَدَّقَ وَأَنْتَ صَحِيحٌ حَرِيصٌ تَأْمُلُ الْبَقَاءَ وَتَخْشَى الْفَقْرَ وَلاَ تُمْهِلْ حَتَّى إِذَا بَلَغَتِ الْحُلْقُومَ قُلْتَ لِفُلاَنٍ كَذَا وَلِفُلاَنٍ كَذَا وَقَدْ كَانَ لِفُلاَنٍ  

The Prophet ﷺ said: A man giving a dirham as sadaqah (charity) during his life is better than giving one hundred dirhams as sadaqah (charity) at the moment of his death.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لأَنْ يَتَصَدَّقَ الْمَرْءُ فِي حَيَاتِهِ بِدِرْهَمٍ خَيْرٌ لَهُ مِنْ أَنْ يَتَصَدَّقَ بِمِائَةٍ عِنْدَ مَوْتِهِ  

The Prophet ﷺ said: A man or a woman acts in obedience to Allah for sixty years, then when they are about to die they cause injury by their will, so they must go to Hell. Then AbuHurayrah recited: "After a legacy which you bequeath or a debt, causing no injury...that will be the mighty success. Abu Dawud said: Al-Ash'ath b. Jabir is the grandfather of Nasr b. 'Ali.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ الرَّجُلَ لَيَعْمَلُ وَالْمَرْأَةَ بِطَاعَةِ اللَّهِ سِتِّينَ سَنَةً ثُمَّ يَحْضُرُهُمَا الْمَوْتُ فَيُضَارَّانِ فِي الْوَصِيَّةِ فَتَجِبُ لَهُمَا النَّارُ قَالَ وَقَرَأَ عَلَىَّ أَبُو هُرَيْرَةَ مِنْ هَا هُنَا { مِنْ بَعْدِ وَصِيَّةٍ يُوصَى بِهَا أَوْ دَيْنٍ غَيْرَ مُضَارٍّ } حَتَّى بَلَغَ { ذَلِكَ الْفَوْزُ الْعَظِيمُ }
