Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "If a person were to know how much sin there is in passing in front of his brother while he is supplicating to his Lord (i.e., performing prayer), then it would be more beloved to him to stand in that place for one hundred years than to take a single step (and pass in front of his brother)."
