Kisah Hikayat Tobatnya Sang Pembunuh 99 Nyawa

There's a story related in Sahih Bukhari emphasising the vastness and generousness of Allah's mercy. The Prophet (saws) picked on certain events throughout history to show their importance. This emphasised a certain message that he was trying to convey to us. Since the events of the past are so numerous, the ones chosen to be related and preserved in his words till the end of time must be of great importance. Whenever we hear stories of the past we should always remember that Allah had chosen those stories to be related as a great occurrence.
