Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: The slave who has made a contract of manumission for one hundred uqiyahs and has paid the entire price except for ten uqiyahs, he will remain a slave; and the slave who has made a contract of manumission for one hundred dinars and has paid all the dinars except for ten dinars, he will remain a slave.
