عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((إِنَّ الْمَسْأَلَةَ لَا تَحِلُّ إِلَّا لِأَحَدِ ثَلَاثٍ: ذِي دَمٍ مُوْجِعٍ، أَوْ غُرْمٍ مُفْظِعٍ، أَوْ فَقْرٍ مُدْقِعٍ))
Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Verily, asking (for charity) is not lawful except for three persons: one who is paying a difficult blood-money, one who is heavily in debt, and one who is extremely poor.
