Sahih al-Bukhari, Volume 3, Book 34, Hadith 413 (USC-MSA) ⓘ
Narrated `Aisha: Hind, the mother of Mu'awiya said to Allah's Messenger, "Abu Sufyan (her husband) is a miser. Am I allowed to take from his money secretly?" The Prophet said to her, "You and your sons may take what is sufficient reasonably and fairly."
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنْ هِشَامٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ هِنْدٌ أُمُّ مُعَاوِيَةَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم إِنَّ أَبَا سُفْيَانَ رَجُلٌ شَحِيحٌ، فَهَلْ عَلَىَّ جُنَاحٌ أَنْ آخُذَ مِنْ مَالِهِ سِرًّا قَالَ " خُذِي أَنْتِ وَبَنُوكِ مَا يَكْفِيكِ بِالْمَعْرُوفِ " .
