سنن النسائي

It was narrated that Abu Al-Aliyah said: "Ibn Abbas said: "On the morning of Al-Aqabah, while he was on his mount, the Messenger of Allah (ﷺ) said to me: "Pick up (some pebbles) for me." So I picked up some pebbles for him that were the size of date stones or fingertips, and when I placed them in his hand he said: "Like these. And beware of going to extremes in religious matters, for those who came before you were destroyed because of going to extremes in religious matters."
