عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يُصَلِّي مِنَ اللَّيْلِ، فَإِذَا انْصَرَفَ قَالَ لِي: ((قُومِي فَأَوْتِرِي))
Sayyidah Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) used to offer prayers at night. When he (peace and blessings be upon him) finished, he would say to me: Get up and offer Witr.
