Musannaf Ibn Abi Shaybah

Hazrat Jabir bin Zaid (may Allah have mercy on him) was asked that a minor girl, after consummation of marriage, was divorced by her husband. She had completed two months and twenty-five days of her waiting period when she started menstruating. What should she do now? He replied that now she should observe the waiting period of three menstrual cycles. Hazrat Abdullah bin Abbas (may Allah be pleased with them both) also used to say the same.
