The Messenger of Allah ﷺ said, "Faith has seventy-odd branches. The lowest of them is removing harm from the road, and the highest is the declaration that there is no god but Allah."
حدثنا أبو كريب حدثنا وكيع عن سفيان عن سهيل بن أبي صالح عن عبد الله بن دينار عن أبي صالح
قال رسول الله ﷺ الإيمان بضع وسبعون بابا أدناها إماطة الأذى عن الطريق وأرفعها قول لا إله إلا الله
