peace,
There is no one verse of Quran that says salat involves all the things you mentioned, i.e. "bowing, prostrating, standing and reciting from the Quran ".
I assume by "bowing" you may be referring to "ruku" which is found in the context of salat in 2:43, however the association is not explicit.
I assume by "prostrating" you may be referring to "sujud" which is found in the context of salat in 4:102. Past discussion:
http://quransmessage.com/forum/index.php?topic=477.45I assume by "standing" you may be referring to "aqimu" which is a command commonly found accompanying the word salat, and it can mean establish/stand/observe/etc.
quran is quite strongly associated with salat however, please see 2:43-45, 4:103, 5:12-13, 7:169-170, 8:2-3, 19:58-59, 29:45, 31:2-7, 33:33-34, 17:78-79, 73:1-4, 73:20.
