We were accompanying the Prophet ﷺ on a journey and I was riding an unmanageable camel belonging to 'Umar (ra), and I could not bring it under my control. So, it used to go ahead of the party and 'Umar would check it and force it to retreat, and again it went ahead and again 'Umar forced it to retreat. The Prophet ﷺ asked 'Umar to sell that camel to him. 'Umar replied, "It is for you O Messenger of Allah !" Messenger of Allah ﷺ told 'Umar to sell that camel to him (not to give it as gift). So, 'Umar sold it to Messenger of Allah ﷺ. Then the Prophet ﷺ said to 'Abdullah bin 'Umar "This camel is for you O 'Abdullah (as a present) and you could do with it whatever you like." (Using translation from Bukhārī 2115)   

كُنَّا مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ وَكُنْتُ عَلَى بَكْرٍ صَعْبٍ لِعُمَرَ وَكَانَ يَغْلِبُنِي فَيَتَقَدَّمُ أَمَامَ الْقَوْمِ فَيُؤَخِّرُهُ عُمَرُ فَيَرُدُّهُ فَقَالَ النَّبِيُّ ﷺ لِعُمَرَ بِعْنِيهِ فَقَالَ هُوَ لَكَ يَا رَسُولَ اللهِ قَالَ بِعْنِيهِ فَبَاعَهُ مِنْ رَسُولِ اللهِ ﷺ فَقَالَ رَسُولُ اللهِ ﷺ هُوَ لَكَ يَا عَبْدَ اللهِ فَاصْنَعْ بِهِ مَا شِئْتَ
