Mishkat al-Masabih, 1931

Abu Huraira reported God’s messenger as saying, “Of a dinar you spend as a contribution in God’s path, or to set free a slave, or as <i>sadaqa</i> given to a poor man, or in support of your family, the one spent in support of your family produces the greatest reward.” Muslim transmitted it.

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «دِينَار أنفقته فِي سَبِيل الله ودينار أنفقته فِي رَقَبَةٍ وَدِينَارٌ تَصَدَّقْتَ بِهِ عَلَى مِسْكِينٍ وَدِينَارٌ أَنْفَقْتَهُ عَلَى أَهْلِكَ أَعْظَمُهَا أَجْرًا الَّذِي أنفقته على أهلك» . رَوَاهُ مُسلم
