وعن ابن عمر رضي الله عنهما قال : قال رسول الله صلى الله عليه وآله وسلم : « صلاة الليل مثنى فإذا خشي أحدكم الصبح صلى ركعة واحدة توتر ما قد صلى» . متفق عليه. وللخمسة وصححه ابن حبان بلفظ : « صلاة الليل والنهار مثنى مثنى » . وقال النسائي : هذا خطأ.
Narrated Ibn 'Umar (RA): Allah's Messenger (ﷺ) said: "The (voluntary) night prayers are two Rak'at, two Rak'at (in pairs), and if one fears that the dawn prayer is due, he should then offer one Rak'at which will make what he has prayed an odd number." [Agreed upon). The Khamsah reported it - graded Sahib (authentic) by Ibn Hibban - with the wording: "the (voluntary) day and night prayers are two Rak'at, two Rak'at (in pairs)." an-Nasa'i said, "This is a mistake."
