Messenger of Allah ﷺ said, "The best object of charity is a she-camel which has (newly) given birth and gives plenty of milk, or a she-goat which gives plenty of milk; and is given to somebody to utilize its milk by milking one bowl in the morning and one in the evening."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ نِعْمَ الصَّدَقَةُ اللِّقْحَةُ الصَّفِيُّ مِنْحَةً وَالشَّاةُ الصَّفِيُّ مِنْحَةً تَغْدُو بِإِنَاءٍ وَتَرُوحُ بِآخَرَ
Messenger of Allah 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.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ نِعْمَ الْمَنِيحَةُ اللِّقْحَةُ الصَّفِيُّ مِنْحَةً وَالشَّاةُ الصَّفِيُّ تَغْدُو بِإِنَاءٍ وَتَرُوحُ بِإِنَاءٍ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ وَإِسْمَاعِيلُ عَنْ مَالِكٍ قَالَ نِعْمَ الصَّدَقَةُ
"نِعْمَ الْمَنيِحَةُ اللِّقْحَةُ الصَفِّيُّ مِنْحَةً، والشَّاةُ مِنحَةً، تَغْدو بِإِنَاءٍ وَتَرُوحُ بِإِنَاءٍ".
