What is the ruling on doubting the number of pebbles for the stoning of the Jamarat, being between 6, 7, and 8?

If someone doubts the number of pebbles while stoning the Jamarah, they should build upon certainty and add the missing number if they suspect a shortage. However, if the doubt occurs after finishing the stoning and leaving the place, then nothing is incumbent upon them, unless they are strongly inclined to believe there was a shortage, in which case they should act according to their strong inclination.
