The Third Martyr (Shaheed Thalith), Qadi Nurullah Shustari
says in Majalisul Momineen: The following lines of poetry are
attributed to the Master of the Age (a.s.), which he composed to
lament the death of Shaykh Mufeed (r.a.) and they can be seen
inscribed on the tombstone of the Shaykh:
There is no call of the caller due to your absence, as it would
be
A day of significance for the progeny of the Messenger.
Even though you may be below the surface of the earth.
So knowledge and monotheism is imbued in you.
And the Qaaem Mahdi is pleased whenever recitation is done
on you.
On you are the lessons of knowledge recited.
Doubt regarding these lines whether they were really
composed by Imam Zamana (a.s.) is same as the previous doubt
and its reply is also same.
