So he -asws said to me...

So he -asws said to me: ‘Or are you in oblivion, or do you not know that Al-Husayn Bin Ali -asws was killed on a day like this! – until he -asws said: ‘O Abdullah Bin Sinan! The best of what you can come up with on a day like this is that you should resort to wearing pure garments and (performs) ‘ Al Tasallab ’. So I said, ‘And what is ‘ Tasallab ’.

Then you should go out to a desolate land, or a place where no one can see you, or resort to an empty land or in privacy, from when the day rises. So you should recite four Cycles, performing the best bowings and the Prostrations, and greetings between each of the two Cycles. Recite in the first Cycle Surah Al Hamd and Al Kafiroun . And in the second Cycle, Al Hamd and Al Ikhlaas .

Then Pray two Cycles at the end recitingin the first Al Hamd and Surah Al Ahzaab , and in the second, Al Hamd and Al Munafiqoun , or whatever is easy (for you) from the Quran, then greetings and turn around your face towards around the grave of Al Husayn -asws and its sleeping place. So you should think of yourself as having been killed along with the ones who were with him -asws from his -asws sons -asws and his -asws family.

And you should send greetings, and Pray to him -asws , and curse his -asws killers, and disavow from their deeds.
