عَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ جَاءَهُ رَجُلٌ فَقَالَ: إِنِّي أُحَدِّثُ نَفْسِي بِالشَّيْءِ لَأَنْ أَكُونَ حُمَمَةً أَحَبُّ إِلَيَّ مِنْ أَنْ أَتَكَلَّمَ بِهِ. قَالَ: «الْحَمْدُ لِلَّهِ الَّذِي رَدَّ أَمْرَهُ إِلَى الْوَسْوَسَةِ» . رَوَاهُ أَبُو دَاوُد

Abu Huraira reported God’s messenger as saying, "Men will continue to question one another till this is propounded

God created all things, but who created God? When they propound that, say, ‘God is one. God is He to whom men repair. He has not begotten and He has not been begotten, and no one is equal to Him.” 1 Then one should spit three times on his left side and seek refuge in God from the accursed devil.” Abu Dawud transmitted it. We shall mention the tradition of ‘Amr b. al-Ahwas in the chapter on the sermon on the day of sacrifice, if God will.1 Book XI; Ch. xi
