The Intended Meaning of "After the Prayer": After the Taslim or Before It?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is the "after the prayer" referred to in the hadith of Abu Umamah? Is it after the taslim or before it?

Answer:
The scholars have differed on the meaning of "after the prayer." The entire period is called "after the prayer," including the end of the prayer and what follows it; all of it is called "after the prayer." However, they say that supplication within the prayer is better than supplication outside the prayer.
