It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever comes to the Friday prayer, let him take a ritual bath." When winter came, it became hard for us, so we complained about it to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Whoever performs ablution has done well, and whoever takes a ritual bath, then the ritual bath is better."
