وَعَنْهُ أَيْضًا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ خَمْسٌ مِنْ حَقِّ الْمُسْلِمِ عَلَى الْمُسْلِمِ رَدُّ التَّحِيَّةِ وَإِجَابَةُ الدَّعْوَةِ وَشُهُودُ الْجَنَازَةِ وَعِيَادَةُ الْمَرِيضِ وَتَشْمِيتُ الْعَاطِسِ إِذَا حَمِدَ اللَّهَ عَزَّ وَجَلَّ
It is narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: A Muslim has five rights over another Muslim: returning the greeting of Salam, accepting an invitation, attending the funeral, visiting the sick, and saying "Yarhamukallah" to the one who sneezes and says "Alhamdulillah."
