All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.
Crying while praying or when reciting the Quran, even if it was for a worldly reason, does not invalidate ablution.
We have already clarified the matters that invalidate ablution in fatwa 84093, so please refer to it.
Allaah knows best.
