from Hajjaj ibn Hajjaj al-Aslami, from his father, who said: I said: O Messenger of Allah, what will remove from me the blame (madhamma) of nursing?

Therefore, it is recommended to make the reward a gift of a soul, to befit the relationship between the blessing and the gratitude. For this reason, Allah the Almighty designated the nursing woman as a mother, as He said: "And your mothers who nursed you" (Quran 4:23). And the Prophet, peace and blessings of Allah be upon him, said: "A child shall not repay his father unless he finds him enslaved and sets him free." If the nursing woman is a slave, it is recommended to emancipate her, because he acquires the most precious of souls through her, and by this, he attains the compensation which the Prophet, peace and blessings of Allah be upon him, established as a compensation for a father by lineage.
