وَحَدَّثَنِي ، عَنْ مَالِك ، أَنَّهُ بَلَغَهُ ، أَنَّ رَجُلًا عَطَسَ يَوْمَ الْجُمُعَةِ وَالْإِمَامُ يَخْطُبُ فَشَمَّتَهُ إِنْسَانٌ إِلَى جَنْبِهِ فَسَأَلَ عَنْ ذَلِكَ سَعِيدَ بْنَ الْمُسَيَّبِ فَنَهَاهُ عَنْ ذَلِكَ ، وَقَالَ : " لَا تَعُدْ "
Imam Malik (may Allah have mercy on him) was informed that a man sneezed on Friday while the Imam was delivering the sermon, and another person replied to him (i.e., said "Yarhamuk Allah"). Then he asked Sa'id ibn al-Musayyib about it, and he forbade it and said: "Do not do that again."
