In my country, the mosques are empty of wells, so in some circumstances we go to the houses of the Christians to ask them for water?

Question:
He says: Honorable Shaykh, may Allah grant you success, I am a scholarship student from one of the African countries, and in our region in Africa, the mosques are empty of wells. We need to pray and we need to perform wudu (ablution), but we have no water, so in some circumstances we go to the houses of the neighboring Christians to ask them for water, and we face various forms of rebuke. Is it permissible for us to perform tayammum (dry ablution) in this situation?

Answer:
If the water is far away and you are unable to bring it, then it is permissible for you to perform tayammum, based on the saying of Allah the Exalted: Yes, and do not go to the Christians while they are threatening you and bestowing favors upon you.
