Sayyid Ibn Tawus, in Iqbal al-A’mal, has mentioned a number of supplicatory prayers and a big number of prayers that are advisably said and offered at this tenth night of Muharram. He has also cited the big rewards of saying and offering these supplications and prayers. For instance, it is recommended to offer a one hundred unit prayer with Surah al-Faatehah once and Surah al-Tawheed three times. After accomplishment, the doxological statements are repeated seventy times:

سُبْحَانَ اللّٰهِ وَ الْحَمْدُ لِلَّهِ وَ لا اِلَهَ اِلا اللّٰهُ وَ اللّٰهُ اَكْبَرُ وَ لا حَوْلَ وَ لا قُوَّةَ اِلا بِاللّٰهِ الْعَلِيِّ الْعَظِيمِ

According to another narration, one should implore for Almighty Allah’s forgiveness after the previously mentioned statements.

It is also recommended to offer a four unit prayer at the last of this night, reciting Surah al-Faatehah once and repeating Ayah al-Kursi and Surahs al-Tawheed, al-Falaq, al-Nas ten times each. After accomplishment, Surah al-Tawheed is repeated one hundred times.

It is also recommended to offer a four unit prayer with Surah al-Faatehah once and Surah al-Tawheed fifty times. Matching the prayer of Imam AliAmeer al-Momineen(a.s.), which brings about a tremendous reward, Sayyid Ibn Tawus says after citing this prayer, “When you finish the fourth units, you may mention Almighty Allah, invoke blessings upon the Holy Prophet and his Household, and curse their enemies as many times as possible.

As regarding the reward of spending this whole night with acts of worship, it has been narrated that one who does so shall be considered having worshipped Almighty Allah with the worship of all the angels. Furthermore, to practice acts of worship at this night is equal to seventy-year worship. Moreover, as for one who succeeds to visit the tomb of Imam al-Husayn (a.s.) at this night and spends the whole night there up to morning, Almighty Allah shall resurrect him, on the Judgment Day, spotted with the blood of Imam al-Husayn (a.s.) in the group of those who were martyred with him.
