 The Tahajjud prayer consists of a minimum of one rakat and the maximum number 11.Some say 13 but any number more than 13 is a bidah (Innovation); for there is no hadeeth; that is saheeh (strong) showing the Muhammad exceeding more than 13 rakats (according to Abu ‘Abdillaah Muhammad ibn Nasr al-Marwazee)

It is recommended that tahajjud be prayed during the last third of the night, but performing it at any other time is better than not performing it at all.Tarawih () is a sunnah muakada night prayer during Ramadan.
