In-book no 2636حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ سُفْيَانَ، عَنْ عُمَارَةَ، عَنْ أَبِي زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَجُلٌ لِلنَّبِيِّ صلى الله عليه وسلم يَا رَسُولَ اللَّهِ، أَىُّ الصَّدَقَةِ أَفْضَلُ قَالَ " أَنْ تَصَدَّقَ وَأَنْتَ صَحِيحٌ حَرِيصٌ. تَأْمُلُ الْغِنَى، وَتَخْشَى الْفَقْرَ، وَلاَ تُمْهِلْ حَتَّى إِذَا بَلَغَتِ الْحُلْقُومَ قُلْتَ لِفُلاَنٍ كَذَا وَلِفُلاَنٍ كَذَا، وَقَدْ كَانَ لِفُلاَنٍ ".
Narrated Abu Huraira: A man asked the Prophet, "O Allah's Messenger (ﷺ)! What kind of charity is the best?" He replied. "To give in charity when you are healthy and greedy hoping to be wealthy and afraid of becoming poor. Don't delay giving in charity till the time when you are on the death bed when you say, 'Give so much to soand- so and so much to so-and so,' and at that time the property is not yours but it belongs to so-and-so (i.e. your inheritors).
