Ahmad b. Ziyad b. Ja`far al-Hamadani narrated to us. He said: `Ali b. Ibrahim narrated to us from his father from Muhammad b. Abi `Umayr from Murazim b. Hakim from al-Sadiq Ja`far b. Muhammad . He said: Betake to going to mosques, for they are the houses of Allah on Earth. Whoever goes to them in a state of purity, Allah purifies him of his sins and records him as one of its visitors. Increase your prayer and supplication in them. Pray in different spots in the mosques, for each spot will bear you witness that you prayed upon it on the Day of Resurrection.
