عَنْ مُحَمَّدِ بْنِ حَمْزَةَ الْأَسْلَمِيِّ أَنَّهُ سَمِعَ أَبَاهُ يَقُولُ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((عَلَى ظَهْرِ كُلِّ بَعِيرٍ شَيْطَانٌ فَإِذَا رَكِبْتُمُوهَا فَسَمُّوا اللَّهَ عَزَّ وَجَلَّ وَلَا تُقَصِّرُوا عَنْ حَاجَاتِكُمْ))
It is narrated from Sayyiduna Hamzah Aslami, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: There is a devil on the back of every camel, so when you ride it, mention the name of Allah Almighty, and then do not be lazy in fulfilling your needs.
