(the Prophet, sal Allaahu alayhi wa sallam ) as saying : Were it not that I might oeverburdern the believers, I would order them to delay the night ('isha ) prayer and use the tooth-stick at the time of every prayer.
أَنْ أَشُقَّ عَلَى الْمُؤْمِنِينَ لأَمَرْتُهُمْ بِتَأْخِيرِ الْعِشَاءِ وَبِالسِّوَاكِ عِنْدَ كُلِّ صَلاَةٍ
