Benefits of the hadith of 'A'ishah: The Prophet (peace and blessings be upon him) used to pray while I was lying across his bed, and when he wanted to pray the witr, he would wake me up so I would pray the witr.

The Shaykh : In this is evidence for cooperation in righteousness and piety, and that a person should encourage his family to pray their witr in the last part of the night, because that is better. However, if it is difficult for the woman to pray the witr in the last part of the night and she prays it in the first part of the night, he should not wake her except for the Fajr prayer. But if there is no hardship, it is better that he wake her so she prays the witr in the last part of the night.
