[Machine] Narrated from the Prophet ﷺ that he used to say to the Muslim regarding his brother four etiquettes: when he calls him, he answers him; when he passes away, he attends his funeral; when he falls ill, he visits him; and when he sneezes, he says to him, "May Allah have mercy on you."
عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يَقُولُ لِلْمُسْلِمِ عَلَى أَخِيهِ أَرْبَعُ خِلَالٍ إِذَا دَعَاهُ أنْ يُجِيبَهُ وَإِذَا مَاتَ أنْ يَشْهَدَهُ وَإِذَا مَرِضَ أنْ يَعُودَهُ وَأنْ يُشَمِّتَهُ إِذَا عَطَسَ
