عَنْ سَعْدِ بْنِ أَبِیْ وَقَّاصٍ أَنَّهُ أَخْبَرَهُ أَنَّ رَسُولَ اللہِ صَلَّى اللہُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّكَ لَنْ تُنْفِقَ نَفَقَةً تَبْتَغِیْ بِهَا وَجْهَ اللہِ إِلَّا أُجِرْتَ عَلَيْهَا حَتَّى مَا تَجْعَلُ فِی فَمِ امْرَأَتِكَ
Hazrat Saadra ibn Abi Waqas relates that the Holy Prophetsa said to him:
“Whatever you might spend seeking thereby the pleasure of Allah will have its reward, even that which you put in the mouth of your wife.”
(Sahih Bukhari, Kitab al-Iman, Hadith 56)
