Sahih Muslim 157 c
Encouragement to give charity before there is no one to accept it
Arabic hadith text
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - وَهُوَ ابْنُ عَبْدِ الرَّحْمَنِ الْقَارِيُّ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ "لاَ تَقُومُ السَّاعَةُ حَتَّى يَكْثُرَ الْمَالُ وَيَفِيضَ حَتَّى يَخْرُجَ الرَّجُلُ بِزَكَاةِ مَالِهِ فَلاَ يَجِدُ أَحَدًا يَقْبَلُهَا مِنْهُ وَحَتَّى تَعُودَ أَرْضُ الْعَرَبِ مُرُوجًا وَأَنْهَارًا "
Translation
Abu Huraira reported Allah's Messenger (way peace be upon him) as saying
The Last Hour will not come before wealth becomes abundant and overflowing, so much so that a man takes Zakat out of his property and cannot find anyone to accept it from him and till the land of Arabia reverts to meadows and rivers.
