It is narrated from Sayyiduna Ali (may Allah be pleased with him) that a man came to the Prophet (peace and blessings be upon him) and said: "I have made a vow that I will slaughter my she-camel and do such-and-such things." He (the Prophet) said: "Slaughter your she-camel, but such-and-such things are from Satan, so leave them."
