Musannaf Ibn Abi Shaybah 34320 — Reports on Sad bin Abi Waqqas

Abu Balj (may Allah have mercy on him) said: I heard Mus'ab bin Sa'd (may Allah have mercy on him) say that Sayyiduna Sa'd (may Allah be pleased with him) made a contract of manumission with a slave of his, and he demanded some money from that slave. The slave said: "I have nothing to give you." And he had gone to some dinars and stitched them into his sandals. So Sayyiduna Sa'd (may Allah be pleased with him) invoked Allah against him, and both his sandals were stolen.
