Majma al-Zawaid 3082 — Going early to the Friday prayer

Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "When it is Friday, the angels sit at the doors of the mosques and record the names of the people according to the order of their arrival. One person is as if he gave a camel in charity, another is as if he gave a cow in charity, another is as if he gave a goat in charity, another is as if he gave a hen in charity, and another is as if he gave an egg in charity." The Prophet (peace and blessings be upon him) said: "When the muezzin calls the adhan and the imam sits on the pulpit, the scrolls are rolled up, and the angels enter the mosque and listen attentively to the remembrance (that is, the sermon)."
Imam Ahmad recorded this narration, and its narrators are thiqat (trustworthy).
