أَبُو عَلِيٍّ الْأَشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ عَلِيِّ بْنِ إِسْحَاقَ عَنْ سَهْلِ بْنِ الْيَسَعِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) مَنْ بَاتَ عَلَى سَطْحٍ غَيْرِ مُحَجَّرٍ فَأَصَابَهُ شَيْءٌ فَلَا يَلُومَنَّ إِلَّا نَفْسَهُ .
2. Abu Ali al-Ash‘ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Ali ibn Ishaq from Sahl ibn al-Yasa’ who has said the following: “Abu ‘Abd Allah 
, has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘One who sleeps on a flat roof without a safety fencing walls around it and if something happened to him, he must not blame anyone except his own soul.”’
