(452) بَابُ حَقُّ الْمُسْلِمِ عَلَى الْمُسْلِمِ أَنْ يُسَلِّمَ عَلَيْهِ إِذَا لَقِيَهُ
Abu Hurayra said, "I heard the Messenger of Allah, may Allah blesshim and grant him peace, say, 'The rights a Muslim has over another Muslimare six." He was asked, "What are they?" He replied, "When he meets him,he should greet him, When he gives him an invitation, he should accept.When he asks him for advice, he should give him good counsel. When he sneezesand praises Allah, he should wish him mercy. when he is ill, he shouldvisit him. When he dies, he should accompany him."
