Al-Waalid, Ash-Shaykh Hasan Abdil-Wahhaab Al-Bannaa, hafidhahullahu ta’aalaa, said that -
the people dont fear Allah because they do not know Him. They are ignorant of Allah so therefore the do not fear Him. The one who is ignorant of Asmaa Allah wa Sifaatihi (Allah’s names and His Attributes) does not fear Allah. The one who does not know that Allah is fauqa Arshihi (above His Throne) does not fear Allah. The one who does not know Shurootu Laa Ilaaha Illa Allah (the conditions of Ash-Shahaadah) does not fear Allah. The one who knows Allah, who has knowledge of Allah’s Names and Attributes, the one who knows the conditions of Kalimatut-Tawheed (the state of the Oneness of Allah), the one who knows where Allah is; this is the one who fears Allah.
