Prophet Yusuf (AS) & Zulaykhaa (raa)
Prophet Yusuf (AS) infallibility was due to The Almighty and Glorious SWT protecting him from sin- not that he himself was incapable of it.
The Proof
• He (as) saw the face of the Azeez of Misr (ra).
• He (as) saw The Sacred Verse of The Surah upon the ceiling (Surah 17 v32).
• He (as) saw his father (as) who struck him on the chest.
• He (as) saw Zulaykhaa's (raa) veneration of her idol.
• The venerable Prophet was protected by Allah SWT.
