Majma al-Zawaid 1737 — The time of Maghrib

Sayyiduna al-Harith bin Wahb (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "My Ummah will remain upon (the teachings of) Islam as long as they do not delay Maghrib until the stars begin to shine, which is the way of the Jews, and as long as they do not offer the Fajr prayer so early, which is the way of the Christians, and as long as they do not leave funerals (janazahs) to the deceased's own family."
Al-Tabarani recorded it in al-Mu'jam al-Kabir. Its chain contains a narrator, Mandal bin Ali, in whom there is weakness. A hadith about its virtue has already passed in the chapter on the middle prayer.
