Zuhayr bin Alqamah (may Allah have mercy on him) relates: A woman of the Ansar came to the Messenger of Allah (peace and blessings be upon him) concerning a son of hers who had died. The people seemed to reproach her, so she said: O Messenger of Allah, besides this one, two children of mine have died since I entered Islam. The Prophet (peace and blessings be upon him) said: "By Allah, you have fenced yourself off from the Fire with a very strong fence."
