Grand Ayatollah Abdollah Javadi Amoli, a Shi'ite religious authority based in the holy city of Qom, said during his weekly ethics session on Wednesday that Islamic tradition recommends the so-called salat al-istisqa, which he described as a prayer for water in all forms, not just rain.
“This prayer, meaning asking for water, is not only for requesting rain but also for the abundance of water in wells, springs, and underground sources,” he said.
Multiple cities in Iran have held or scheduled rain-seeking prayers this week in response to a dramatic drop in rainfall and depleted river and reservoir levels.
In Tehran, the prayer will be held on Friday at 15:00 at the shrine of Imamzadeh Saleh Shrine in north Tehran, led by Ayatollah Seyyed Jamal al‑Din Din Parvar according to state media reports.
In Qom in central Iran the ceremony is scheduled for Friday morning at the Grand Mosque, as announced by provincial officials.
