It is narrated from Sayyiduna Mu'adh that the Prophet (peace and blessings be upon him) said: Whoever builds a building in such a way that no one is wronged or harmed, or plants a tree so that no one is wronged or harmed, he will receive the reward of ongoing charity as long as the creation of Allah continues to benefit from it.
