Tafsir Ibn Kathir -> Surah An-Nisa -> Spending on the Unwise with Fairness

Allah said,

﴿وَارْزُقُوهُمْ فِيهَا وَاكْسُوهُمْ وَقُولُواْ لَهُمْ قَوْلاً مَّعْرُوفاً﴾

(but feed and clothe them therewith, and speak to them words of kindness and justice.) `Ali bin Abi Talhah said that Ibn `Abbas commented, "Do not give your wealth, what Allah has made you responsible for and made a means of sustenance to you, to your wife or children. Rather, hold on to your money, take care of it, and be the one who spends on them for clothes, food and provision.'' Mujahid said that the Ayah,

﴿وَقُولُواْ لَهُمْ قَوْلاً مَّعْرُوفاً﴾

(and speak to them words of kindness and justice.) refers to kindness and keeping good relations. This honorable Ayah commands kind treatment, in deed, with family and those under one's care. One should spend on them for clothes and provisions, and be good to them, such as saying good words to them.
