نا بحر بن نصر ، نا عبد الله بن وهب ، قال: وحدثني معاوية بن صالح ، ان عبد الله بن ابي قيس حدثه، انه سال عائشة زوج النبي صلى الله عليه وسلم: كيف كان رسول الله صلى الله عليه وسلم يوتر، آخر الليل او اوله؟ قالت: كل ذلك قد كان يفعل، ربما " اوتر اول الليل وربما اوتر من آخره ، فقلت: الحمد لله الذي جعل في الامر سعة"
Sayyiduna Abdullah bin Qais narrates that he asked the noble wife of the Prophet, Sayyidah Aisha (may Allah be pleased with her), how the Messenger of Allah (peace and blessings be upon him) used to perform Witr—did he offer it at the end of the night or at the beginning of the night? She replied that he (peace and blessings be upon him) used to offer it in every part. Sometimes he would offer it at the beginning of the night, and sometimes he would perform it in the last part of the night. So I said, all praise is due to Allah who has placed ease and flexibility in this matter.
