Modesty [haya’] is part of faith

عَنْ‭ ‬أَبِي‭ ‬هُرَيْرَةَ‭ ‬ـ‭ ‬رضى‭ ‬اللّٰه‭ ‬عنه‭ ‬ـ‭ ‬عَنِ‭ ‬النَّبِيِّ‭ ‬صلّى‭ ‬اللّٰه‭ ‬عليه‭ ‬وسلّم‭ ‬قَالَ:‭ ‬الإِيمَانُ‭ ‬بِضْعٌ‭ ‬وَسِتُّونَ‭ ‬شُعْبَةً،‭ ‬وَالْحَيَاءُ‭ ‬شُعْبَةٌ‭ ‬مِنَ‭ ‬الإِيمَانِ.‏

Hazrat Abu Hurairah^ra narrated, “The Prophet^sa said, ‘Faith has over sixty branches, and modesty is one of the branches of faith.’”
