The Prophet (PBUHH) was quoted as saying: “If a person stays vigilant in the Night of Qadr and is a believer in the day of rewards and punishments, then all his sins will be forgiven [14] .” IV) Descent of Angels: According to verses of Qur’an 97, angels and the Spirit descend on the Earth on the Night of Qadr (Qur’an 97:4) and according to some hadiths, they meet the Imam to notify him of what is predestined for people in the coming year.
Imam al-Bāqir (PBUH) said: “On this night, angels circumambulate around us, whereby we find out that it is the Night of Qadr [15] .” Time of the Night of Qadr Shia Muslims similarly believe that Laylat al-Qadr is to be found in the last ten odd-numbered nights of holy month of Ramadan but mostly on the 19th, 21st, or 23rd of Ramadan with the 23rd being the most important night.
The 19th, according to Shia belief, coincides with the night Ali was attacked in the Mihrab while worshipping in the Great Mosque of Kufa. He died on 21 Ramadan. According to other hadiths, destinies are written on the night of Ramadan 19, are finalized on the night of Ramadan 21, and are ultimately confirmed on the night of Ramadan 23 [16] .
Recommended acts of Laylat al-Qadr The recommended acts of the Qadr Nights are of two parts; the first part deals with the general acts that are advisably practiced at each of the three Qadr Nights. The second part deals with the private acts that are dedicated to each night exclusively. GENERAL ACTS These are the recommended acts of worship common to all three nights (19th, 21st, and 23rd nights).
These include: First: It is recommended to have a ritual bath (Ghusl) oneself at each of the Qadr Nights. According to ‘Allamah al-Majlisī, it is preferable to perform the bathing at sunset to be ready for the Isha’ Prayer with bathing. Second: It is recommended to offer a two-unit prayer reciting at each unit Surah al-Fatihah once and repeating Surah al-Tawhīd seven times.
