Sahih al-Bukhari, Hadith 5849 ⓘ
Narrated Al-Bara: The Prophet ordered us to observe seven things: To visit the sick; follow funeral processions; say 'May Allah bestow His Mercy on you', to the sneezer if he says, 'Praise be to Allah!; He forbade us to wear silk, Dibaj, Qassiy and Istibarq (various kinds of silken clothes); or to use red Mayathir (silkcushions). (See Hadith No. 253 A, Vol. 8).
حَدَّثَنَا قَبِيصَةُ، حَدَّثَنَا سُفْيَانُ، عَنْ أَشْعَثَ، عَنْ مُعَاوِيَةَ بْنِ سُوَيْدِ بْنِ مُقَرِّنٍ، عَنِ الْبَرَاءِ ـ رضى الله عنه ـ قَالَ أَمَرَنَا النَّبِيُّ صلى الله عليه وسلم بِسَبْعٍ عِيَادَةِ الْمَرِيضِ، وَاتِّبَاعِ الْجَنَائِزِ، وَتَشْمِيتِ الْعَاطِسِ، وَنَهَانَا عَنْ لُبْسِ الْحَرِيرِ، وَالدِّيبَاجِ، وَالْقَسِّيِّ، وَالإِسْتَبْرَقِ، وَمَيَاثِرِ الْحُمْرِ.
