Sayyiduna Abdullah bin Amr (may Allah be pleased with him) says: As bin Wa'il made a vow in the days of ignorance that he would slaughter one hundred camels (but he died before fulfilling the vow). His son Hisham bin As slaughtered fifty camels from his share, and the other son, Sayyiduna Amr, asked the Noble Prophet (peace and blessings of Allah be upon him) about this. The Prophet (peace and blessings of Allah be upon him) said: "If your father had affirmed the oneness of Allah and you had fasted or given charity on his behalf, it would have benefited him."
