مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ يَحْيَى عَنْ غِيَاثِ بْنِ إِبْرَاهِيمَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) إِنَّ عَلَى ذِرْوَةِ كُلِّ بَعِيرٍ شَيْطَاناً فَامْتَهِنُوهَا لِأَنْفُسِكُمْ وَ ذَلِّلُوهَا وَ اذْكُرُوا اسْمَ اللَّهِ فَإِنَّمَا يَحْمِلُ اللَّهُ عَزَّ وَ جَلَّ .

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Yahya from Ghiyath ibn Ibrahim who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has stated this Hadith. ‘On the peak of every camel there is a Satan and you must degrade him before yourselves by mentioning the name of Allah, only Allah, most Majestic, most Glorious is He who carries loads.’”
