It was narrated from 'Abdullah bin 'Amr bin al-As that the Messenger of Allah said to a man:
I have been instructed to take the Day of Sacrifice as an 'Id which Allah, the Might and Sublime, has ordained for this Ummah. The man said: What do you think if I cannot find anything but a female sheep that has been loaned to me so that I may benefit from its milk - should I sacrifice it? He said: No. Rather cut something from your hair and your nails, trim your mustache and shave your pubic hairs, and you will have a complete reward with Allah, the Might and Sublime, as if you had offered the sacrifice.
