"During the Farewell Hajj, while the Messener of allah was standing at Arafat, a Bedouin came to him begging while pulling on the edge of his Rida. He gave him something and he left. With that, begging was made unlawful, so the Messenger of Allah said: 'Begging is not lawful for the rich nor for the physically fit, except for the one who is severely poor or in perilous debt. And whoever begs the people (merely) to increase his wealth, then on the Day of Judgment (the wealth he begged for) will be lacerations on his face and heated coals from Hell will be provided for him to eat. Whoever wishes, let him take a little, and whoever wishes, then let him take a lot.'"
حَدَّثَنَا عَلِيُّ بْنُ سَعِيدٍ الْكِنْدِيُّ، حَدَّثَنَا عَبْدُ الرَّحِيمِ بْنُ سُلَيْمَانَ، عَنْ مُجَالِدٍ، عَنْ عَامِرٍ الشَّعْبِيِّ، عَنْ حُبْشِيِّ بْنِ جُنَادَةَ السَّلُولِيِّ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي حَجَّةِ الْوَدَاعِ وَهُوَ وَاقِفٌ بِعَرَفَةَ أَتَاهُ أَعْرَابِيٌّ فَأَخَذَ بِطَرَفِ رِدَائِهِ فَسَأَلَهُ إِيَّاهُ فَأَعْطَاهُ وَذَهَبَ فَعِنْدَ ذَلِكَ حَرُمَتِ الْمَسْأَلَةُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِنَّ الْمَسْأَلَةَ لاَ تَحِلُّ لِغَنِيٍّ وَلاَ لِذِي مِرَّةٍ سَوِيٍّ إِلاَّ لِذِي فَقْرٍ مُدْقِعٍ أَوْ غُرْمٍ مُفْظِعٍ وَمَنْ سَأَلَ النَّاسَ لِيُثْرِيَ بِهِ مَالَهُ كَانَ خُمُوشًا فِي وَجْهِهِ يَوْمَ الْقِيَامَةِ وَرَضْفًا يَأْكُلُهُ مِنْ جَهَنَّمَ فَمَنْ شَاءَ فَلْيُقِلَّ وَمَنْ شَاءَ فَلْيُكْثِرْ .
