Vowing to slaughter a camel if her sons had children and then she slaughtered 7 sheep instead

A: The vow of the questioner has been fulfilled by slaughtering seven sheep instead of slaughtering the camel she had vowed to slaughter. Muslim scholars (may Allah be merciful to them) have agreed on the permissibility of doing this. Ibn Qudamah is one of the scholars who held this view. He states in his book Al-Mughni, "If a person makes a vow to slaughter a camel, then slaughters seven sheep instead, it will be sufficient." In the offering of Hady (sacrificial animal offered by pilgrims) and Ud-hiyah (sacrificial animal offered by non-pilgrims), a sheep is known to be equal to one-seventh of a camel. Besides, the meat of sheep is more delicious than camel meat. It is better to leave what is good for the sake of doing what is better. Anyway it is permissible to slaughter seven sheep instead of a camel or a cow or to slaughter a cow instead of seven sheep in case one is obliged to.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
