الْأَدَبُ الْمُفْرَدُ
Al-Adab al-Mufrad 925
Sneezing and Yawning
Wishing mercy on the sneezer
وَعَنْ إِسْمَاعِيلَ بْنِ جَعْفَرٍ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم قَالَ: حَقُّ الْمُسْلِمِ عَلَى الْمُسْلِمِ سِتٌّ، قِيلَ: مَا هِيَ يَا رَسُولَ اللهِ؟ قَالَ: إِذَا لَقِيتَهُ فَسَلِّمْ عَلَيْهِ، وَإِذَا دَعَاكَ فَأَجِبْهُ، وَإِذَا اسْتَنْصَحَكَ فَانْصَحْ لَهُ، وَإِذَا عَطَسَ فَحَمِدَ اللَّهَ فَشَمِّتْهُ، وَإِذَا مَرِضَ تَعُودُهُ، وَإِذَا مَاتَ فَاتَّبِعْهُ.
Abu Hurayra reported that the Messenger of Allah, (ﷺ), said, "A Muslim owes another Muslim six duties." He was asked, "And what are they, Messenger of Allah?" He said, "To greet him when he meets him, to accept when he gives him an invitation, to give him good counsel when he asks for advice, to wish mercy on him when he sneezes and says, 'Praise be to Allah,' to visit him when he is ill, and to join the funeral procession when he dies."
