Musannaf Ibn Abi Shaybah 21071 — Killing geckos

Uqbah bin Fakih said: I came to Sayyiduna Zayd bin Thabit (may Allah be pleased with him) at midday. I asked permission to come in, and he came out wearing a lower wrap (izar), holding a stick in his hand. I said: What are you doing at this time? He said: I am looking for this creature; for killing it Allah Almighty records a good deed and forgives a sin. So kill it; that creature is the gecko.
