The Prophet (ﷺ) said, "The width between the two shoulders of a Kafir (disbeliever) will be equal to the distance covered by a fast rider in three days."
Sahih al-Bukhari Book 81, Hadith 140
← Previous Hadith Haritha was martyred on the day (of the battle) of Badr while he was young. His mother came to the Prophet (ﷺ) saying, "O Allah's Messenger (ﷺ)! You know the relation of Haritha to me (how fond of him I was); so, if he is in Paradise, I will remain patient and wish for Allah's reward, but if he is not there, then you will see what I will do." The Prophet (ﷺ) replied, "May Allah be merciful upon you! Have you gone mad? (Do you think) it is one Paradise? There are many Paradises and he is in the (most superior) Paradise of Al-Firdaus."

Sahih al-Bukhari Book 81, Hadith 139 Next Hadith → Allah's Messenger (ﷺ) said, "In Paradise there is a tree so big that in its shade a rider may travel for one hundred years without being able to cross it."
