Bayhaqi 1732 — Those who said Maghrib has two times

Sulayman bin Buraydah narrates from his father (may Allah be pleased with him) that a man came to the Prophet (peace and blessings be upon him) and asked about the times of prayer. He (peace and blessings be upon him) said: "Pray with us at these two times." When the sun had declined, he (peace and blessings be upon him) ordered Bilal (may Allah be pleased with him), and he called the adhan; then he (peace and blessings be upon him) ordered, and he called the iqamah for Zuhr; then he (peace and blessings be upon him) ordered, and he called the iqamah for Asr while the sun was high, white and clear; then he (peace and blessings be upon him) ordered, and he called the iqamah for Maghrib when the edge of the sun had disappeared; then he (peace and blessings be upon him) ordered, and he called the iqamah for Isha when the redness of twilight had disappeared; then he (peace and blessings be upon him) ordered, and he called the iqamah for Fajr when the dawn had broken. When the next day came, he (peace and blessings be upon him) ordered, and he called the iqamah for Zuhr, and he (peace and blessings be upon him) delayed it until it was thoroughly cool; then he ordered, and he called the iqamah for Asr while the sun was white, and he (peace and blessings be upon him) delayed it beyond what it had been before; and he ordered, and he called the iqamah for Maghrib before the redness of twilight disappeared; and he (peace and blessings be upon him) ordered, and he called the iqamah for Isha when a third of the night had passed; and then he (peace and blessings be upon him) ordered, and he called the iqamah for Fajr, and he prayed it in the light. Then he (peace and blessings be upon him) said: "(This is) the time of your prayer, as you have seen."
Abu Ayyub added in his narration: Then he (peace and blessings be upon him) said: "Where is the one who asked about the time of prayer?" The man said: I am (here), O Messenger of Allah! He (peace and blessings be upon him) said: "The time of your prayer is between what you have seen."
In the 'Ilal of Abu Isa al-Tirmidhi it is reported from al-Bukhari that he said: The hadith of Abu Musa is hasan, and the hadith of al-Thawri from Alqamah bin Marthad from Ibn Buraydah from his father on the prayer times is a hasan hadith.
