"And hold fast, all together, by the rope which Allah (stretches out for you), and be not divided among yourselves; and remember with gratitude Allah’s favour on you; for you were enemies and He joined your hearts in love, so that by His Grace, you became brothers; and you were on the brink of the pit of Fire, and He saved you from it. Thus Allah make His Signs clear to you: That you may be guided." (Qur'an, 3:103)
Imam Ghazali told story of a man walking in the jungle. A roaring lion ran towards him and the man ran as fast as he could to escape from it. He noticed a well in front of him and he jumped inside hoping to escape from the lion.
As he was falling inside the well, he grabbed onto the rope and saved himself. The man was so relieved but when he looked down he saw a big snake at the bottom of the well. It had its jaws wide open ready to swallow him up.
The man then looked up and saw two mice nibbling at the rope. A black mouse and a white were both chewing into the rope. The scary lion was still prowling outside the well.
