Narrated Abu As-Sawar Al-Adawi:

`Imran bin Husain said: The Prophet (ﷺ) said, "Haya' (pious shyness from committing religeous indiscretions) does not bring anything except good." Thereupon Bashir bin Ka`b said, 'It is written in the wisdom paper: Haya' leads to solemnity; Haya' leads to tranquility (peace of mind)." `Imran said to him, "I am narrating to you the saying of Allah's Messenger (ﷺ) and you are speaking about your paper (wisdom book)?"

حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ أَبِي السَّوَّارِ الْعَدَوِيِّ، قَالَ سَمِعْتُ عِمْرَانَ بْنَ حُصَيْنٍ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ الْحَيَاءُ لاَ يَأْتِي إِلاَّ بِخَيْرٍ ‏"‏‏.‏ فَقَالَ بُشَيْرُ بْنُ كَعْبٍ مَكْتُوبٌ فِي الْحِكْمَةِ إِنَّ مِنَ الْحَيَاءِ وَقَارًا، وَإِنَّ مِنَ الْحَيَاءِ سَكِينَةً‏.‏ فَقَالَ لَهُ عِمْرَانُ أُحَدِّثُكَ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم وَتُحَدِّثُنِي عَنْ صَحِيفَتِكَ‏.‏
