وَعَنْ عَبْدِاللَّهِ بْنِ سَلَامٍ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا جَلَسَ يَتَحَدَّثُ يُكْثِرُ أَنْ يَرْفَعَ طَرْفَهُ إِلَى السَّمَاء. رَوَاهُ أَبُو دَاوُد
Translation
`Abdallah b. Salam said that when God's messenger sat talking he would often raise his eyes to the sky. Abu Dawud transmitted it.
