Hadith 3:86
Abu Huraira reported God's messenger as saying, “Were it not that I might distress my people, I would order them to delay the evening prayer and use the tooth stick at every time of prayer.” (Bukhari and Muslim.)
عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَوْلَا أَنْ أَشُقَّ عَلَى أُمَّتِي لَأَمَرْتُهُمْ بِتَأْخِيرِ الْعشَاء وبالسواك عِنْد كل صَلَاة»
