Abu Hurayrah reported that the Prophet ﷺ said:
الْإِيمَانُ بِضْعٌ وَسَبْعُونَ شُعْبَةً وَالْحَيَاءُ شُعْبَةٌ مِنَ الْإِيمَانِ (Sahih Muslim: 35a)
Meaning: Faith has seventy-some parts, and ḥayāʾ (modesty)1 is a part of faith.
This is an example of gharīb Hadith because some generations in its transmission have just one narrator.
1. Ḥayāʾ (حیا): a sense of modesty that encourages good and restrains a person from wrongdoing.
