Ibn Shihab narrated from Salim bin Abdullah, from his father, from the Prophet ﷺ:
Ibn Shihab said: “Salim read to me a letter that the Messenger of Allah had written concerning Sadaqat, before Allah caused him to pass away, in which it was said: 'For five camels one sheep; for ten, two sheep; for twenty, four sheep. For twenty five, a Bint Makhad(a one year old she-camel), up to thirty-five; if there is no Bint Makhad, then a Bin Labun ( a two-year-old male camel). If there are more than thirty-five even one, then a Bint Labun ( a two-year-old she-camel) must be given up to forty-five. If there are more than forty-five, even one, then a Hiqqah (a three-year-old she-camel), up to sixty camels. If there are more than sixty, even one more, then a Jadha'ah ( a four-year-old she-camel) must be given, up to seventy-five. If there are more than seventy-five, even one more, then two Bint Labun must be given, upto ninety. If there are more than ninety, even one more, then two Hiqqah must be given, up to one hundred and twenty. If there are many camels, then for each fifty, one Hiqqah must be given and for each forty a Bint Labun' ”
