Sayyiduna Jarir (may Allah be pleased with him) said: Uyaynah bin Hisn came to the Prophet (peace and blessings be upon him), and a man was with him. That (man) asked for water, so water was brought, and he drank it while concealed (behind a screen). Uyaynah asked: What is this? He said: "It is modesty and faith; they have been given it, and you have been deprived of it."
