The twenty-first night of Ramadan is more meritorious that the nineteenth. It is worthwhile to practice the previously mentioned general rites of the Qadr Nights, such as bathing, spending the whole nights with acts of worship, visiting the tomb of Imam al-Husayn (a.s.), offering the two unit prayer at which Surah al-Faatehah is recited once and Surah al-Tawheed repeated seven times, putting a copy of the Holy Qur’an on the head and saying the supplication dedicated to this practice, saying the Dua al-Jawshan al-Kabir supplicatory prayer, and so on. According to narrations, it is strongly advisable to do the bathing and to spend the whole night with painstaking acts of worship at this night as well as the twenty-third, since the real Qadr Night is one of these two nights.
When the Holy Infallibles (a.s.) were asked to specify the Qadr Night, they did not specify; rather they used to say, “It is too easy to act at two nights in order to win one’s desire.” They also used to say, “What will harm you if you do righteously at two nights?”
Dictating to his students, Shaykh al-Saduq said in one of his sessions, “It is preferable to spend these two nights with studying the religious knowledge.”
Starting with this night, it is recommended to say the supplicatory prayers that are dedicated to the last ten nights of Ramadan.
