4ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ أَتَى رَجُلٌ النَّبِيَّ (صلّى اللهُ عَلَيْهِ وَآلِه) فَقَالَ يَا رَسُولَ الله أَشْكُو إِلَيْكَ مَا أَلْقَى مِنَ الْوَسْوَسَةِ فِي صَلاَتِي حَتَّى لاَ أَدْرِي مَا صَلَّيْتُ مِنْ زِيَادَةٍ أَوْ نُقْصَانٍ فَقَالَ إِذَا دَخَلْتَ فِي صَلاَتِكَ فَاطْعُنْ فَخِذَكَ الأيْسَرَ بِإِصْبَعِكَ الْيُمْنَى الْمُسَبِّحَةِ ثُمَّ قُلْ بِسْمِ الله وَبِالله تَوَكَّلْتُ عَلَى الله أَعُوذُ بِالله السَّمِيعِ الْعَلِيمِ مِنَ الشَّيْطَانِ الرَّجِيمِ فَإِنَّكَ تَنْحَرُهُ وَتَطْرُدُهُ.
4. Ali ibn Ibrahim has narrated from his father from al-Nawfaliy from al-Sakuniy who has said the following: “Abu ‘Abd Allah , has said, ‘Once a man came to the Holy prophet, and said, “O Messenger of Allah, I complain before you against misgivings I face in my Salah (prayer) so much so that I do not know how much I have performed, increased or decreased. He (the Messenger of Allah) said, ‘When you begin your Salah (prayer) hit your left thigh with your right forefinger and say, ‘In the name of Allah, I choose Allah, the all-knowing and all-hearing as my attorney against Satan, condemned to be stoned, thus, you slaughter and repel him.’”
