[Machine] When the people of Quba asked the Prophet ﷺ to build a mosque for them, the Messenger of Allah ﷺ said, "Let someone among you bring a camel." Abu Bakr stood up and brought a camel, but when he tried to make it move, it did not respond. So he returned and sat down. Then Umar stood up and brought a camel, but it also did not respond when he tried to make it move. So he returned and sat down. Then the Messenger of Allah ﷺ said to his companions, "Let someone among you bring a camel." Ali stood up and when he placed his foot on the stirrup, the Messenger of Allah ﷺ said, "O Ali, hold its reins and build upon its hump, for it is instructed to obey."

لَمَّا سَأَلَ أَهْلُ قُبَاءٍ النَّبِيَّ ﷺ أَنْ يَبْنِيَ لَهُمْ مَسْجِدًا فَقَالَ رَسُولُ اللهِ ﷺ «لِيَقُومَ بَعْضُكُمْ فَيَرْكَبَ النَّاقَةَ» فَقَامَ أَبُو بَكْرٍ ؓ فَرَكِبَهَا فَحَرَّكَها فَلَمْ تَنْبَعِثْ فَرَجَعَ فَقَعَدَ فَقَامَ عُمَرُ ؓ فَرَكِبَهَا فَحَرَّكَها فَلَمْ تَنْبَعِثْ فَرَجَعَ فَقَعَدَ ثُمَّ قَالَ رَسُولُ اللهِ ﷺ لِأَصْحَابِهِ «لِيَقُومَ بَعْضُكُمْ فَيَرْكَبَ النَّاقَةَ» فَقَامَ عَلِيٌّ ؓ فَلَمَّا وَضَعَ رِجْلَهُ فِي غَرَزِ الرِّكَابِ وَثَبَّتَ بِهِ قَالَ رَسُولُ اللهِ ﷺ «يَا عَلِيُّ إِرْخِ زِمَامَهَا وَابْنُوا عَلَى مَدَارِها فَإِنَّهَا مَأْمُورَةٌ»
