“TAQŠǏR” of the Obligatory Prayers and Performing Voluntary Prayers During Ziyārah — Hadith 4

4. My father narrated to me from Sa’d ibn ‘Abdillāh, from Aḥmad ibn Muḥammad ibn ‘Isā, from ‘Ali ibn Ismā’īl, from Safwān ibn Yaḥyā, from Isḥāq ibn ‘Ammār, who said: I asked Abal Ḥasan (Imam Kāżim (a. s. )) if a Muqassir can establish voluntary prayers next to the grave of Ḥusain (a. s. ), at (different holy) sites of the Prophet (s. a. a. w. ), and in the two Ḥarams. Imam (a. s. ) replied, “Yes. Establish as many voluntary prayers as you can for it is a blessing. ”
