What is meant by Ibn 'Abbas's statement, "I used to know the end of the Prophet's (peace and blessings be upon him) prayer by the takbir"?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: The hadith of Ibn 'Abbas (may Allah be pleased with them both) in Sahih al-Bukhari states: . Does this mean that we say "Allahu Akbar" three times after the prayer before the istighfar? Or do we delay the takbir until after the istighfar?

Answer:
The takbir referred to here is the dhikr that is recited after the prayer and said aloud. This is what is meant by the takbir. It is the dhikr of Allah that includes the tahlil, tasbih, tahmid, and takbir after the prayers. Ibn 'Abbas was young at the time, and they knew that the Prophet's (peace and blessings be upon him) prayer had ended when they heard the takbir, or when they heard the dhikr after the prayer, they knew the prayer was over. This is evidence for raising the voice in the dhikr after the prayer. Yes.
