Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said, "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."[Al-Bukhari and Muslim].
