Narrated Sahl bin Sa'd (Radi-Allahu 'anhu):
Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) 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."
Hadrat Anas Radi ALLAH Taala Anhu reported that the Messenger of Allah Peace And Blessings Be Upon Him has said, “Everything has a heart, and the heart of the Qur’an is Yasin. Allah records anyone who recites Yasin as having recited the Qur’an ten times.”
