وَتَجَاوَزَ إِلَى مَوْضِعٍ يَلْحَقُهُ حُكْمُ التَّطْهِيرِ
Translation: And it moves beyond to a place where the legal requirement of purification applies.
Tajāwuz means movement beyond the initial point of exit. If a bead of blood appears on the wound but remains stationary, the condition of flowing has not ordinarily been met.
