Shaykh Rabee Bin Hadi al-Madkhali [حفظه الله] said: ❝It is obligatory to have great importance of Tawheed. I swear by Allaah that this Ummah did not become lost and its enemies did not prevail over them from the Jews Christians, Majoos, socialists and others except after they lost Tawheed. So Allaah caused this humiliation to overcome them and He is not pleased with them until they return to the Islaam which Muhammad [ﷺ] and his noble Companions were upon.❞ [Nafhaat Al-Huda Wal-Eemaan]
