Hind bint ʿUtba (Abu Sufyan's wife) came and said, "O Messenger of Allah ﷺ! Abu Sufyan is a miser. Is there any harm if I spend something from his property for our children?" He said, there is no harm for you if you feed them from it justly and reasonably (with no extravagance).  

يَا رَسُولَ اللَّهِ إِنَّ أَبَا سُفْيَانَ رَجُلٌ مِسِّيكٌ فَهَلْ عَلَىَّ حَرَجٌ أَنْ أُطْعِمَ مِنَ الَّذِي لَهُ عِيَالَنَا فَقَالَ لاَ حَرَجَ عَلَيْكِ أَنْ تُطْعِمِيهِمْ بِالْمَعْرُوفِ  

Hind came to the Prophet ﷺ and said: Messenger of Allah, Abu Sufyan is a stingy person. Is there any harm to me if I spend on his dependants from his property without his permission ? The Prophet ﷺ replied: There is no harm to you if you spend according to the custom.  

جَاءَتْ هِنْدٌ إِلَى النَّبِيِّ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ أَبَا سُفْيَانَ رَجُلٌ مُمْسِكٌ فَهَلْ عَلَىَّ مِنْ حَرَجٍ أَنْ أُنْفِقَ عَلَى عِيَالِهِ مِنْ مَالِهِ بِغَيْرِ إِذْنِهِ فَقَالَ النَّبِيُّ ﷺ لاَ حَرَجَ عَلَيْكِ أَنْ تُنْفِقِي عَلَيْهِمْ بِالْمَعْرُوفِ
