Sunan Abi Dawud 5001
‘Uthman b. Abu 'Atikah said :
The only reason why he asked whether the whole of him should come in was because of the smallness of the tent
حَدَّثَنَا صَفْوَانُ بْنُ صَالِحٍ، حَدَّثَنَا الْوَلِيدُ، حَدَّثَنَا عُثْمَانُ بْنُ أَبِي الْعَاتِكَةِ، قَالَ إِنَّمَا قَالَ أَدْخُلُ كُلِّي ‏.‏ مِنْ صِغَرِ الْقُبَّةِ ‏.‏
