When the Messenger of Allah ﷺ sat talking (to the people), he would often raise his eyes to the sky.  

أبو داود:٤٨٣٧حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ يَحْيَى الْحَرَّانِيُّ قَالَ حَدَّثَنِي مُحَمَّدٌ يَعْنِي ابْنَ سَلَمَةَ عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ عَنْ يَعْقُوبَ بْنِ عُتْبَةَ عَنْ عُمَرَ بْنِ عَبْدِ الْعَزِيزِ عَنْ يُوسُفَ بْنِ عَبْدِ اللَّهِ بْنِ سَلاَمٍ عَنْ أَبِيهِ قَالَ

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا جَلَسَ يَتَحَدَّثُ يُكْثِرُ أَنْ يَرْفَعَ طَرْفَهُ إِلَى السَّمَاءِ
