What is the meaning of "whoever praises Allah one hundred times will have the reward of one hundred bridled horses," and does the reward apply to those who praise fifty times, or is it limited to one hundred?

Imam Ahmad reported from Umm Hani' that the Messenger of Allah, may Allah bless him and grant him peace, advised her to glorify Allah one hundred times (say "SubhanAllah"), to praise Allah one hundred times (say "Alhamdulillah"), to declare Allah's oneness one hundred times (say "La ilaha illa Allah"), and to magnify Allah one hundred times (say "Allahu Akbar"). The meaning of praising Allah one hundred times is that its reward is equivalent to equipping one hundred horses for jihad in the way of Allah. As for determining the reward for praising Allah fifty times, there is no text regarding this, and estimating rewards is not a matter for personal reasoning. However, whoever does good deeds will be rewarded for them with goodness.
