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].
