Imam used to recite special supplications narrated by the holy prophet and his infallible sucessors on various occasions.
For an example, each of the special days or the blessed months such as Rajab, Sha’aban and blessed fasting month of Ramadan got specific supplications which have been recommended for believers and faithful people for recitation.
Imam had a great amount of devotion towards these supplications and recited the contents of “Maftihl al-Jinan”, which is a collection of the spplication narrated by infallible Imam and contains a treasure of great divine-oriented mysticism,
Imam used to recite various supplications to such an extent that resulted in decay of the book and he had to change or buy the collection of prayers once or twice a year.
