Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī

ذِكْرُ الْبَيَانِ بِأَنَّ الْمُصْطَفَى ﷺ كَانَ إِذَا أَوْتَرَ بِثَلَاثٍ فَصَلَ بَيْنَ الثِّنْتَيْنِ وَالْوَاحِدَةِ بِتَسْلِيمَةٍ

[Machine] The Prophetﷺ used to separate between the two units of prayer known as "Shaf'a" and "Witr" by uttering the "tasleem" out loud for us to hear.  

ابن حبّان:٢٤٣٤ – أَخْبَرَنَا الْحَسَنُ بْنُ سُفْيَانَ قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ قَالَ حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ عَنِ الْوَضِينِ بْنِ عَطَاءٍ عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ عَنْ أَبِيهِ قَالَ

«كَانَ النَّبِيُّ ﷺ يَفْصِلُ بَيْنَ الشَّفْعِ وَالْوِتْرِ بِتَسْلِيمٍ يُسْمِعُنَاهُ»

Collected by Ibn Ḥibbān

ذِكْرُ مَا يُسْتَحَبُّ لِلْمَرْءِ رَفْعُ الصَّوْتِ بِالتَّسْلِيمِ بَيْنَ شَفْعِهِ وَوِتْرِهِ مِنْ صَلَاتِهِ
