Narrated Abu As-Sawar Al-Adawi:
‘Imran bin Husain said, “The Prophet said, ‘Haya’ 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 Apostle and you are speaking about your paper (wisdom book)?”
