122 - وَ سَأَلَ عَلِيُّ بْنُ جَعْفَرٍ أَخَاهُ مُوسَى بْنَ جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلرَّجُلِ يَسْتَاكُ مَرَّةً بِيَدِهِ إِذَا قَامَ إِلَى صَلاَةِ اَللَّيْلِ وَ هُوَ يَقْدِرُ عَلَى اَلسِّوَاكِ فَقَالَ «إِذَا خَافَ اَلصُّبْحَ فَلاَ بَأْسَ بِهِ.
Hadith.122 - Ali ibn Ja'far asked his brother Imam Musa ibn Jafar Al-Kadhim 
bout a man who uses his hand to clean his teeth when he gets up for the night prayer (Salat Al Layl), even though he has access to siwak.
Imam said: "If he fears that dawn is approaching, there is no harm in doing so."
