And if you are doubtful in the case of your women who are despair of periodical menstruation, then their waiting period is for three months, and of those who have not yet menstruation as well; the waiting period of the pregnant women is the delivery of her pregnancy, whoever heeds Allah, he will get remedy for any of his problem.
This verse mentions about the waiting period mentioned in the first verse “If you are divorcing your wives, then you divorce them for the ‘waiting period’”. As told in the verse 2: 28, generally the waiting period is for continuous three menstruation period. But it is fixed to three months of lunar calendar. Since the waiting period of the pregnant woman is fixed to the delivery of her pregnancy, she should be sent from the house only after the delivery of her pregnancy. As told in verses 92: 5-7, whoever testifies Adhikr, Allah will make easy everything to Him. See explanation 2: 234; 39: 33-36; and 64: 15-16.
