Surah an-Nisa, 4:64) The belief of Muhammad interceding is found in various hadith as well. A Bedouin of the desert visited the Prophet's tomb and greeted the Prophet, addressing him directly as if he were alive. "Peace upon you, Messenger of God!" Then he said, "I heard the word of God 'If, when they had wronged themselves . . .,' I came to you seeking pardon for my mistakes, longing for your intercession with our Lord!" The Bedouin then recited a poem in praise of the Prophet and departed. The person who witnessed the story says that he fell asleep, and in a dream he saw the Prophet saying to him, "O 'Utbi, rejoin our brother the Bedouin and announce [to] him the good news that God has pardoned him!" Syrian Islamic scholars Salih al-Nu'man, Abu Sulayman Suhayl al-Zabibi, and Mustafa ibn Ahmad al-Hasan al-Shatti al-Hanbali al-Athari al-Dimashqi have similarly released Fatwas in support of the practice. Al-Suyuti in his book History of the Caliphs also reports Caliph Umar's prayer for rain after the death of Muhammad and specifies that on that occasion 'Umar was wearing his mantle (al-burda), a detail confirming his tawassul through Muhammad at that occasion. Sahih al-Bukhari narrates similar situation as: Hadith states that on that day people will be running to and fro looking for an intercessor, until they come to the Prophet Muhammad, who will answer, "I am for intercession". The Lord will then ask him to "...intercede, for your intercession will be heard" (Bukhari). Sunni Muslims of this movement also commonly say Ya Rasool Allah ('O Messenger of Allah'), addressing Muhammad in the present tense with the belief that he is able to listen. They believe that Muhammad is a Rahmah (mercy) to all creation as mentioned in the Quran . Muhammad therefore is a means by which God expresses his attribute, Ar-Rahman, to creation. Light of Muhammad (Nur Muhammadiyya) A central doctrine of this movement is that Muhammad is both human and (Noor) light. Muhammad's physical birth was preceded by his existence as a light which predates creation. The primordial reality of Muhammad existed before creation, and God created for the sake of Muhammad. Adherents of this doctrine believe that the word Nur (light) in the Quran refers to Muhammad. Sahl al-Tustari, the ninth-century Sunni Quran commentator, describes the creation of Muhammad's primordial light in his tafsir. Mansur Al-Hallaj (al-Tustari's student) affirms
