'Abdullah ibn al-Khatami reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Every act of kindness is sadaqa."  

قَالَ رَسُولُ اللهِ ﷺ كُلُّ مَعْرُوفٍ صَدَقَةٌ  

Anas said, "When the Prophet, may Allah bless him and grant him peace, was given something, he used to say, 'Take it to so-and-so. She was a friend of Khadija's. Take it to the house of so-and-so. She loved Khadija."  

عَنْ أَنَسٍ قَالَ كَانَ النَّبِيُّ ﷺ إِذَا أُتِيَ بِالشَّيْءِ يَقُولُ اذْهَبُوا بِهِ إِلَى فُلاَنَةٍ فَإِنَّهَا كَانَتْ صَدِيقَةَ خَدِيجَةَ اذْهَبُوا بِهِ إِلَى بَيْتِ فُلاَنَةٍ فَإِنَّهَا كَانَتْ تُحِبُّ خَدِيجَةَ  

Same as 231, but from Hudhayfa.  

قَالَ نَبِيُّكُمْ ﷺ كُلُّ مَعْرُوفٍ صَدَقَةٌ
