عَن كَعْب بْنِ مَالِكٍ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ يَوْمَ الْخَمِيسِ فِي غَزْوَةِ تَبُوكَ وَكَانَ يُحِبُّ أَنْ يَخْرُجَ يَوْمَ الْخَمِيسِ. رَوَاهُ البُخَارِيّ

Abu Huraira reported God’s Messenger as saying, “The angels do not go along with a travelling company in which there is a dog or a bell." Muslim transmitted it.
