Musnad Abu Ya'la al-Mawsili 160:90

And with his chain of narration, that the Messenger of Allah (may Allah bless him and grant him peace) said: "While a man was walking on a road, he saw a thorny branch, so he said: 'By Allah, I will surely remove this so that it does not afflict any of the Muslims.' So he removed it, and Allah forgave him."
