Al-Adab Al-Mufrad, Hadith 444 ⓘ
Abu'l-'Ubaydayn said, "I asked 'Abdullah about those who squander and he said, 'They are those who spend incorrectly.'"
حَدَّثَنَا قَبِيصَةُ، قَالَ: حَدَّثَنَا سُفْيَانُ، عَنْ سَلَمَةَ، عَنْ مُسْلِمٍ الْبَطِينِ، عَنْ أَبِي الْعُبَيْدَيْنِ قَالَ: سَأَلْتُ عَبْدَ اللهِ عَنِ الْمُبَذِّرِينَ، قَالَ: الَّذِينَ يُنْفِقُونَ فِي غَيْرِ حَقٍّ.
