“By the night when it veils (all things with darkness), by the day when it appears radiant”
Mohammed bin Muslim said, I asked Imam Baqir (as) about the verse, “By the night when it veils (all things with darkness)”.
Imam (as) replied, “The night” in this verse refers to the second (caliph) who betrayed the Commander of the Believers (as) with his government. However, the Commander of the Believers (as) stayed patient until the end of their government.
I asked about the verse, “By the day when it appears radiant”
Imam (as) replied, “The day” refers to our Qaem (as) who will overcome falsehood through his government at the time of his rising.
Then Imam (as) added, Allah uses examples in the Qur’an. The Qur’an is addressed to the Prophet (sawa) and to us. Therefore, no one understands it but us. (Tafseer Al Qummi page 425)
