Sunan Abi Dawud, 4853
sahih· Al-Albani

Abu Salih said:

I was sitting with my father and there was also a boy with him. He got up and then returned. So my father mentioned a tradition on the authority of Abu Hurairah from the Prophet (ﷺ) saying: If anyone gets up from where he has been sitting and comes back to it, he has most right to it.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، قَالَ كُنْتُ عِنْدَ أَبِي جَالِسًا وَعِنْدَهُ غُلاَمٌ فَقَامَ ثُمَّ رَجَعَ فَحَدَّثَ أَبِي، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏

‏ إِذَا قَامَ الرَّجُلُ مِنْ مَجْلِسٍ ثُمَّ رَجَعَ إِلَيْهِ فَهُوَ أَحَقُّ بِهِ ‏
