Shaykh Abdul-Muhsin Al-Abbaad was asked:

Question:

Is it allowed for the one who is living in the lands of disbelief, and he is an Imam, to pray the rain prayer when there is a need? This is for the Muslims who are residents [there].

Answer:

“It is allowed for him to do that”.

[Sharh Sunan Tirmidhi no. 78]
