Hadith 11:35
Waki’ narrated to us, [saying] narrated to us Mughira ibn Ziyad, from Makhul, who said: A man came to the Prophet, may Allah bless him and grant him peace, and said: "O Messenger of Allah, the people have gone out on a military expedition, and something has detained me, so guide me to a deed that will make me catch up with them." He said: "Are you able to stand [in prayer] during the night?" He said: "I would struggle with that." He said: "Are you able to fast during the day?" He said: "Yes." He said: "For your reviving of your night and your fasting of your day is like the sleep of one of them."
حدثنا وكيع نا مغيرة بن زياد عن مكحول قال جاء رجل إلى النبي صلى الله عليه وسلم فقال يا رسول الله إن الناس قد غزوا وحبسني شيء فدلني على عمل يلحقني بهم قال هل تستطيع قيام الليل قال أتكلف ذلك قال هل تستطيع صيام النهار قال نعم قال فإن إحياءك ليلتك وصيامك نهارك كنومة أحدهم
