حَدَّثَنَا إِسْمَاعِيلُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللهِ بْنِ عُمَرَ، أَنَّهُ كَانَ إِذَا عَطَسَ فَقِيلَ لَهُ‏:‏ يَرْحَمُكَ اللَّهُ، فَقَالَ‏:‏ يَرْحَمُنَا اللَّهُ وَإِيَّاكُمْ، وَيَغْفِرُ لَنَا وَلَكُمْ‏.‏

Iyas ibn Salama related that his father said, "A man sneezed in the presence of the Prophet, may Allah bless him and grant him peace, and the Prophet said, 'May Allah have mercy on you.' Then the man sneezed again and the Prophet, may Allah bless him and grant him peace, said, 'This man has a cold.'"
