Cut something from your hair & nails; Trim your mustache; Shave your pubic hairs

The hadith is about taking the Day of Sacrifice as an 'Id which Allah has ordained for this Ummah. It was narrated by Abdullah bin Amr bin al-As that the Messenger of Allah said to a man that if he cannot find anything but a female sheep that has been loaned to him so that he may benefit from its milk, then instead of sacrificing it, he should cut something from his hair and nails, trim his mustache and shave his pubic hairs. This will be rewarded with Allah's grace as if one had offered the sacrifice. This hadith teaches us about being mindful in our actions towards fulfilling religious obligations while also being considerate towards animals. We can learn from this hadith that even small acts can be rewarded greatly by Allah when done with sincerity and faithfulness.
