Anas narrated: "A man sought a mount from the Messenger of Allah who said: 'Indeed, I will let you ride on a she-camel's child.' So he said: 'O Messenger of Allah! What can ashe-camel's child do?' So the Messenger of Allah said: 'Are camels borne from other than she-camels?'"
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ الْوَاسِطِيُّ، عَنْ حُمَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَجُلاً، اسْتَحْمَلَ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ " إِنِّي حَامِلُكَ عَلَى وَلَدِ النَّاقَةِ " . فَقَالَ يَا رَسُولَ اللَّهِ مَا أَصْنَعُ بِوَلَدِ النَّاقَةِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " وَهَلْ تَلِدُ الإِبِلَ إِلاَّ النُّوقُ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ .
