عن أم سلمة رضي الله عنها قالت قال رسول الله صلى الله عليه وسلم ‏:‏ ‏"‏من كان له ذبح يذبحه، فإذا أهل هلال ذي الحجة، فلا يأخذن من شعره ولا من أظفاره شيئًا حتى يضحي‏"‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏

Umm Salamah (May Allah be pleased with her) said

The Messenger of Allah (ﷺ) said, "When anyone of you intends to sacrifice the animal and enter in the month of Dhul-Hijjah, he should not get his hair cut or nails pared till he has offered his sacrifice."[Muslim].
