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 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. (Using translation from Abū Dāʾūd 2866)   

أَنَّ النَّبِيَّ ﷺ قَالَ «لِأَنْ يَتَصَدَّقَ الْمَرْءُ فِي حَيَاتِهِ وَصِحَّتِهِ بِدِرْهَمٍ خَيْرٌ لَهُ مِنْ أَنْ يَتَصَدَّقَ بِمِائَةِ دِرْهَمٍ عِنْدَ مَوْتِهِ» *
