حَدَّثَنَا الْحُمَيْدِيُّ حَدَّثَنَا سُفْيَانُ حَدَّثَنَا إِسْحَاقُ بْنُ سَعِيدٍ السَّعِيدِيُّ عَنْ أَبِيهِ عَنْ أُمِّ خَالِدٍ بِنْتِ خَالِدٍ قَالَتْ قَدِمْتُ مِنْ أَرْضِ الْحَبَشَةِ وَأَنَا جُوَيْرِيَةٌ فَکَسَانِي رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ خَمِيصَةً لَهَا أَعْلَامٌ فَجَعَلَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ يَمْسَحُ الْأَعْلَامَ بِيَدِهِ وَيَقُولُ سَنَاهْ سَنَاهْ قَالَ الْحُمَيْدِيُّ يَعْنِي حَسَنٌ حَسَنٌ
صحیح بخاری · Hadith 3875
Narrated `Abdullah: We used to greet the Prophet while he used to be in prayers, and he used to reply to our greetings. But when we came back from Najashi (the King of Ethiopia) we greeted him (while he was praying) and he did not reply to us. We said, "O Allah's Apostle! We used to greet you in the past and you used to reply to us." He said, "Verily The Mind is occupied and busy with more important matter during the prayer." (So one cannot return One's greetings.)
