صحيح البخاري

Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, "What a good Maniha (the she-camel which has recently given birth and which gives profuse milk) is, and (what a good Maniha) (the sheep which gives profuse milk, a bowl in the morning and another in the evening) is!"

Narrated Malik:

Maniha is a good deed of charity.
