Ata' bin Yasar (may Allah have mercy on him) said: I asked Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him), the Companion of the Messenger of Allah (peace and blessings be upon him): How were the sacrifices among you in the time of the Messenger of Allah (peace and blessings be upon him)? He said: In the time of the Prophet (peace and blessings be upon him), a man would sacrifice a single sheep on behalf of himself and his household; then they would eat from it themselves and feed others as well. Then people began to boast to one another, and the matter became as you see.
