Zaid b. Khalid al-Juhani decided to watch one night what prayers God’s Messenger said. He prayed two short <i>rak'as</i>, then two long, long, long <i>rak'as</i>, then he prayed two <i>rak'as</i> which were less than the two preceding, then he prayed two <i>rak'as</i> which were less then the two preceding, then he prayed two <i>rak'as</i> which were less than the two preceding, then he prayed two <i>rak'as</i> which were less than the two preceding, then he prayed a single one, making a total of thirteen. Muslim transmitted it. The words “then he prayed two <i>rak'as</i> which were less than the two preceding”, mentioned four times, occur thus in Muslim’s <i>Sahih</i> and among those peculiar or him in Humaidi’s book, also in Malik’s <i>Muwatta’</i>, Abu Dawud’s <i>Sunan</i>, and <i>Jami’ al-Usul</i>.

وَعَن زيد بن خَالِد الْجُهَنِيّ أَنَّهُ قَالَ: لَأَرْمُقَنَّ صَلَاةَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اللَّيْلَةَ فَصَلَّى رَكْعَتَيْنِ خَفِيفَتَيْنِ ثُمَّ صَلَّى رَكْعَتَيْنِ طَوِيلَتَيْنِ طَوِيلَتَيْنِ طَوِيلَتَيْنِ ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُمَا دُونَ اللَّتَيْنِ قَبْلَهُمَا ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُمَا دُونَ اللَّتَيْنِ قَبْلَهُمَا ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُمَا دُونَ اللَّتَيْنِ قَبْلَهُمَا [ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُمَا دُونَ اللَّتَيْنِ قَبْلَهُمَا] ثُمَّ أَوْتَرَ فَذَلِكَ ثَلَاثَ عَشْرَةَ رَكْعَةً. رَوَاهُ مُسْلِمٌ قَوْله: ثمَّ صلى رَكْعَتَيْنِ وهما دون اللَّتَيْنِ قَبْلَهُمَا أَرْبَعَ مَرَّاتٍ هَكَذَا فِي صَحِيحِ مُسْلِمٍ وأفراده من كتاب الْحميدِي وموطأ مَالك وَسنَن أبي دَاوُد وجامع الْأُصُول
