Malik related to me from Ibn Shihab from al-Araj from Abu Hurayrathat the Messenger of Allah, may Allah bless him and grant him peace,said, "No one should prevent his neighbour from fixing a wooden peg inhis wall." Then Abu Hurayra said, "Why do I see you turning away fromit? By Allah! I shall keep on at you about it." (IT)
