Greatest Master, Muhammad, and he is the Quran that God mentioned and said:
{"The month of Ramadan in which was revealed the Quran..."} 1
So the month is Abd Allah, and the Quran is Muhammad. And the meaning of: "in which was revealed the Quran" is his appearance and his manifestation that he appeared from Abd Allah, and that is the day of breaking the fast (Eid al-Fitr) and his making lawful all that Abd Allah had made unlawful in it.
As for the thirty days of the month of Ramadan, they are: four children of the Master, the Messenger of God, Muhammad, and they are: Al-Qasim, Al-Tahir, and Abd Allah (his children from Khadija bint Khuwaylid) and Ibrahim (from Maryam the Copt).
And three children of Abu Talib, who are: Talib, Aqil, and Ja'far.
