Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن جابر رضي الله عنه قال: سئل رسول الله صلى الله عليه وسلم : أي الصلاة أفضل؟ قال: "طول القنوت" ((رواه مسلم)).
The Messenger of Allah (ﷺ) was asked: "Which Salat is the best?" He replied, " The best Salat is that in which Qiyam (the duration of standing) is longer."[Muslim].
