Guidance 1
Allah's Messenger said: When any of you sneezes, he should say: ” اَلْحَمْدُ لِلّٰهِ ““All praise is for Allah.” And his friend or brother should say: ” يَرْحَمُكَ اللّٰهُ ““May Allah have mercy on you”. And when his brother says this, the one who sneezed should say: ”يَهْدِيْكُمُ اللّٰهُ وَيُصْلِحُ بَالَكُمْ“ “May Allah guide you and set your affairs right.”
