Obtained this useful reminder from The Book of Assistance by Imam alHaddad (may Allah be pleased with him and our teachers who have translated his work and the students who have benefited therein. Allahumma Ameen):
And Ali, may God ennoble his face, has said:
The one who recites the Qur’an while standing in prayer receives one hundred rewards for each letter; the one who recites it outside the prayer but in a state of ritual purity receives twenty-five rewards for each letter; and those who recite it without ritual purity receive ten rewards for each letter.
Alhumdulillah there’s benefit in every state.
