Sayyidina Abu Kahash (RA) narrated; I took six month old lambs to Madinah (to sell them). But, they were a dead stock for me. I met Abu Hurayrah (RA) and I asked him and he said, “I had heard Allah’s Messenger (SAW) say that the best sacrifice is a six month old lamb.” So, the people took away everything (quickly).
