Is it permissible for me to extend electricity from the mosque to my house after obtaining municipal approval and paying the cost of the electricity to the mosque, despite the objection of one of the sheikhs, knowing that the extension does not harm the mosque?

The shaykh should not prevent the extension of electricity from the mosque if the competent authorities approve it and no harm results from it, because that contradicts cooperation and kindness towards the neighbor. Malik, Bukhari, and Muslim narrated from Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "None of you should prevent his neighbor from placing a piece of wood in his wall." Some scholars have gone to the extent of saying that enabling the neighbor to do so is obligatory, and extending electricity is easier than placing a piece of wood. Umar ibn al-Khattab (may Allah be pleased with him) ordered Muhammad ibn Maslamah to allow al-Dahhak ibn Khalifah to pass a canal through his land. The shaykh has no right to prevent benefiting from the mosque's electricity if it is under the supervision of the competent authorities and will not result in any harm.
