Question
Where is this virtue from?
“Want the reward of setting a slave free? Give milk!”
Answer
This is deduced from the Hadith recorded in Sunan Tirmidhi, Sahih Ibn Hibban and other Hadith collections wherein Nabi (sallallahu ‘alayhi wa sallam) mentioned that whoever lends someone an animal to use its milk or gives someone milk to drink will be rewarded similar to freeing a slave.
(Sunan Tirmidhi, Hadith: 1957, Sahih Ibn Hibban; Al Ihsan, Hadith: 5096)
