Hadith 10:1068
Abu Bakr narrated to us, he said: Umar ibn Zur'ah narrated to us, from Ibn Salim, from al-Sha'bi, that he used to say: If her husband dies while she is a slave, and she attains emancipation while she is still in her waiting period, she completes four months and ten days.
حدثنا أبو بكر قال نا عمر بن زرعة عن بن سالم عن الشعبي أنه كان يقول إذا توفي عنها زوجها وهي مملوكة فأدركها العتق وهي في عدتها [ تتم ] أربعة أشهر وعشرا
