It is narrated from Hazrat Anas (may Allah be pleased with him) that Hazrat Mu'adh (may Allah be pleased with him) used to lead his people in prayer. On one occasion, he was leading the prayer when Hazrat Haram (may Allah be pleased with him), who was going to water his garden, entered the mosque to pray. When he saw that Hazrat Mu'adh (may Allah be pleased with him) was making the prayer long, he shortened his own prayer and went to water his garden. When Hazrat Mu'adh (may Allah be pleased with him) completed the prayer, someone informed him that Hazrat Haram (may Allah be pleased with him) had come to the mosque.
