Anas b. Malik reported to them (his companions) that Allah's Messnger ﷺ had granted concession to Abd al-Rahman b. *Anf and Zubair b. 'Awwam for the wearing of a silk shirt during the journey and because of itch which they both had or any other disease from which both of them had been suffering.  

أَنَّ رَسُولَ اللَّهِ ﷺ رَخَّصَ لِعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ وَالزُّبَيْرِ بْنِ الْعَوَّامِ فِي الْقُمُصِ الْحَرِيرِ فِي السَّفَرِ مِنْ حِكَّةٍ كَانَتْ بِهِمَا أَوْ وَجَعٍ كَانَ بِهِمَا  

This hadith has been narrated on the authority of Sa'd with the same chain of transmitters but there is no mention of the word" journey".  

حَدَّثَنَا سَعِيدٌ بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ فِي السَّفَرِ  

Anas reported that Messenger of Allah ﷺ granted concession, or Zubair b. Awwam and 'Abd Al-Rahman b. Auf were granted concession, for the wearing of silk because of the itch that they both had.  

رَخَّصَ رَسُولُ اللَّهِ ﷺ أَوْ رُخِّصَ لِلزُّبَيْرِ بْنِ الْعَوَّامِ وَعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ فِي لُبْسِ الْحَرِيرِ لِحِكَّةٍ كَانَتْ بِهِمَا  

This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters.  

حَدَّثَنَا شُعْبَةُ بِهَذَا الإِسْنَادِ مِثْلَهُ  

Anas b. Malik reported that 'Abd al-Rahman b. Auf and Zu'bair. b. 'Awwam complained to Messenger of Allah ﷺ about lice; he granted them concession to wear shirts of silk.  

أَخْبَرَهُ أَنَّ عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ وَالزُّبَيْرَ بْنَ الْعَوَّامِ شَكَوَا إِلَى رَسُولِ اللَّهِ ﷺ الْقَمْلَ فَرَخَّصَ لَهُمَا فِي قُمُصِ الْحَرِيرِ فِي غَزَاةٍ لَهُمَا
