Sahih Muslim · Hadith 1804

حدثنا عبد بن حميد، أخبرنا أبو عاصم، أخبرنا ابن جريج، أخبرني أبو الزبير، عن جابر، قال قال رسول الله صلى الله عليه وسلم ‏"‏ أفضل الصلاة طول القنوت ‏"‏ ‏.‏

Jabir reported: The Messenger of Allah (may peace be upon him) was asked about the prayer which was most excellent. He said: That in which the standing is longer. (This hadith is narrated by another chain of transmitters too.)
