حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ حُمَيْدٍ، عَنْ بَكْرِ بْنِ عَبْدِ اللَّهِ، عَنْ عَبْدِ اللَّهِ بْنِ رَبَاحٍ، عَنْ أَبِي قَتَادَةَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا كَانَ فِي سَفَرٍ فَعَرَّسَ بِلَيْلٍ اضْطَجَعَ عَلَى يَمِينِهِ وَإِذَا عَرَّسَ قُبَيْلَ الصُّبْحِ نَصَبَ ذِرَاعَهُ وَوَضَعَ رَأْسَهُ عَلَى كَفِّهِ .
Ishaq ibn Ibrahim reported to us: Sulayman ibn Harb reported to us: Hammad ibn Salamah reported to us, from Humayd, from Bakr ibn Abdullah, from Abdullah ibn Rabah, from Abu Qatadah, who said: When the Messenger of Allah (ﷺ) stopped during a journey at night, he would lie on his right side. When he stopped shortly before dawn, he would prop up his forearm and rest his head on his palm.
