A slave being given charity

Ziyad bin Abi Maryam narrates from his mother that she said: I came to Sayyiduna Abdullah bin al-Arqam (may Allah be pleased with him). He was in charge of the treasury (Bayt al-Mal) during the rule of Sayyiduna Umar and Sayyiduna Uthman (may Allah be pleased with them both), and he was distributing the sadaqah (zakah) in Madinah. When he saw me, he said: What has brought you here, O Umm Ziyad? I said: The same thing that has brought the people. He asked: Have you been freed yet? I said: No. So he sent someone to his house, and a cloak was brought, and he had it given to me, but he did not have anything from the sadaqah (zakah) given to me, because I was a slave at that time.

Mujahid said: Do not feed these black (slaves) from your sacrificial animals, for they are only the property of the people of Makkah.

It is narrated from Layth that Salim disliked giving sadaqah to the slaves of the Bedouins.
