عن أبي سعيد الخدري رضي الله عنه أن رسول الله صلى الله عليه وسلم قال: «من أدركه الصبح ولم يوتر؛ فلا وتر له».
This narration shows that the time for the Witr prayer expires after daybreak and that this is the normal time range for it. However, if someone wakes up from sleep late, then the time for the Witr is extended for him until the Fajr prayer, as it was reported to have been done by a great number of the Companions (may Allah be pleased with them).
