[Machine] The Messenger of Allah ﷺ used to teach us that when one of you sneezes, they should say, "Alhamdulillah, Lord of the worlds." And when they say that, they should also say, "May Allah have mercy on you." And when they say that, they should also say, "May Allah forgive me and you."
كَانَ رَسُولُ اللهِ ﷺ يُعَلِّمُنَا إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلِ الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ فَإِذَا قَالَ ذَلِكَ فَلْيَقُلْ مَنْ عِنْدَهُ يَرْحَمُكَ اللهُ فَإِذَا قَالَ فَلْيَقُلْ يَغْفِرُ اللهُ لِي وَلَكُمْ
