Riyad as-Salihin: The Book of Good Manners - Iman has sixty odd or seventy odd branches. The uppermost of all these is the Testimony of Faith: 'La ilaha illallah' (there is no true god except Allah) while the least of them is the removal of harmful object from the road. And shyness is a branch of Iman. Messenger of Allah was even shier than a virgin behind her veil. When he saw something which he disliked, we could perceive it on his face.
