The requirement of the imam's permission for the prayer for rain

Question:
He says: Honorable Shaykh, may Allah grant you success, does the prayer for rain necessarily require the permission of the general imam?

Answer:
It depends on the need. If the people of a town or a group need to seek rain for their need, even if they are traveling, and seeking rain is not limited to the prayer. Seeking rain by supplication alone, without prayer, is done by gathering and raising their hands and calling upon Allah to give them rain, whether they are sitting or standing. Ibn al-Qayyim mentioned that seeking rain is of three types. The first type is the well-known seeking rain, which is the prayer and supplication after the prayer, as the Prophet (peace and blessings be upon him) did.
The second type is that they supplicate while sitting without raising their voices, as the Prophet (peace and blessings be upon him) did on some occasions. The third type is seeking rain in the Friday sermon, as the Prophet (peace and blessings be upon him) did. The Prophet (peace and blessings be upon him) did all three of these. It is not limited to the prayer; one seeks rain according to his need.
