حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا ابْنُ فُضَيْلٍ عَنْ الْأَعْمَشِ عَنْ إِبْرَاهِيمَ عَنْ عَلْقَمَةَ عَنْ عَبْدِ اللَّهِ قَالَ کُنْتُ أُسَلِّمُ عَلَی النَّبِيِّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ فِي الصَّلَاةِ فَيَرُدُّ عَلَيَّ فَلَمَّا رَجَعْنَا سَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيَّ وَقَالَ إِنَّ فِي الصَّلَاةِ َشُغْلًا
صحیح بخاری · Hadith 1216
Narrated `Abdullah: I used to greet the Prophet while he was in prayer and he would return my greeting, but when we returned (from Ethiopia) I greeted the Prophet (while he was praying) but he did not return the greeting, and (after finishing the prayer) he said, "In the prayer one is occupied (with a more serious matter)."
