Praise be to
Allaah.
The
author of Zaad al-Mustaqni’ said: “If it (the sacrifice) gets
injured (develops a flaw), it may still be slaughtered and this will
do…”
Shaykh Ibn ‘Uthaymeen said: an example of that is
when a man buys a sheep to sacrifice it, then it breaks its leg and
is unable to walk and keep up with the rest of the flock, after he has
selected it for sacrifice. In this case it may be slaughtered and this
will do, because when it was selected it became a trust, like something
that was entrusted to him. Because it is something entrusted and the
injury was not the result of his action or his negligence, so he is
not obliged to offer any guarantee, and it will do.
See al-Sharh al-Mumti’, part 7, p. 515
