It was narrated that Anas bin Malik said:
“The Prophet (ﷺ): 'When anyone of you asks his neighbor for permission to fix a piece of wood to his wall, he should not refuse him. 'When Abu Hurairah told them this, they lowered their heads, and when he saw them he said: 'Why do I see you turning away from it? By Allah, I will force you to accept it.' ”
