Narrated Ibn Abbas (Radi-Allahu 'anhu):
On the Day of the Conquest of Makkah, Allah's Apostle (Sallallahu 'Alaihi
Wa Sallam) said, "Allah has made this town a sanctuary. Its thorny bushes
should not be cut, its game should not be chased, and its fallen things
should not be picked up except by one who would announce it publicly."
Bukhari Vol. 2 : No. 657
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.”
