The venerable Upāli asked the Blessed Buddha, “Reverend, if a person who has maliciously drawn blood from a tathāgata wants monkhood, to go forth and be ordained in the well-proclaimed Dharma and Vinaya in the Blessed One’s presence, should his going forth be allowed or not?”

“Upāli, his going forth should not be allowed. Therefore, if someone wishing to go forth approaches any of you, you should ask, ‘You have not maliciously drawn blood from a tathāgata, have you?’ If you allow going forth without asking this, a breach occurs.”
