عَنْ أَبِي لَاسٍ الْخُرَاعِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ: حَمَلَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَلَى إِبِلٍ مِنْ إِبِلِ الصَّدَقَةِ ضِعَافٍ إِلَى الْحَجِّ، قَالَ: فَقُلْنَا: يَا رَسُولَ اللَّهِ إِنَّ هَٰذِهِ الْإِبِلَ ضِعَافٌ، نَخْشَى أَنْ لَا تَحْمِلَنَا، قَالَ: فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((مَا مِنْ بَعِيرٍ إِلَّا فِي ذِرْوَتِهِ شَيْطَانٌ فَارْكَبُوهُنَّ، وَاذْكُرُوا اسْمَ اللَّهِ عَلَيْهِنَّ كَمَا أُمِرْتُمْ ثُمَّ امْتَهِنُوهُنَّ لِأَنْفُسِكُمْ فَإِنَّمَا يَحْمِلُ اللَّهُ عَزَّ وَجَلَّ))
Sayyiduna Abu Las Khuzai (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) made us ride weak camels given as charity for Hajj. We said: O Messenger of Allah, these camels are weak, we fear that they may not be able to carry us. He (peace and blessings be upon him) said: There is a devil on the hump of every camel, so when you are about to mount them, mention the name of Allah as you have been commanded, then use them for your service. Surely, it is Allah alone who makes them carry (i.e., He creates the strength and patience in these camels to bear the load).
