One of the actions that the late Ayatollah Bahjat Quds-Sara was committed to doing on Friday evenings was reciting the Salawat of Zarrab Isfahani, which was narrated from the Imam of the Age (peace be upon him). (Bahjat al-Duaa, p. 177; This supplication is also mentioned at the beginning of Mafatih al-Jinan, p. 103, in the Friday prayers).
