It is narrated from Sayyiduna Abu Mas'ud al-Ansari (may Allah be pleased with him) that I said: From the Prophet (peace and blessings be upon him)? He said: (It is narrated) from the Prophet (peace and blessings be upon him): "When a Muslim spends on his family seeking reward for it, it is recorded for him as charity." Imam Bukhari (may Allah have mercy on him) recorded it in his Sahih, and Imam Muslim (may Allah have mercy on him) recorded it through two other chains from Shu'bah.
