If you are quoting verses within a manuscript, the copyright information needs to be added in a footnote and/or bibliography:  Saheeh International, The Qur’an: English Meanings and Notes, Riyadh: Al-Muntada Al-Islami Trust, 2001-2011; Jeddah: Dar Abul-Qasim 1997-2001.  If the work is less formal, you can use this statement instead:  ”The Qur’anic quotations contained herein are from the Saheeh International translation.”
