Hadith.2072 - Ali ibn Ja'far asked his brother Imam Musa ibn Jafar Al-Kadhim (as) about a mukatab (a slave who has a contract to earn their freedom):
"Is Zakat al-Fitr obligatory upon the mukatab or upon the one who wrote the contract of emancipation for him? And is his testimony valid?"
Imam (as) replied: "Zakat al-Fitr is obligatory upon him (the mukatab), but his testimony is not valid."
