Hazrat Kadeer al-Dhahi narrates that a man came to the service of the Prophet Muhammad (peace be upon him) and said, "O Messenger of Allah (peace be upon him), tell me of a deed that will admit me to Paradise?" The Prophet (peace be upon him) said: "Speak with justice and give charity from your surplus wealth." He said, "O Messenger of Allah (peace be upon him), what if I am unable to do this?" The Prophet (peace be upon him) said: "Do you have camels?" He replied, "Yes." The Prophet (peace be upon him) said: "Take one of your camels, keep a water-skin with it, and give water to those people who get water only every other day. Surely, before your camel becomes exhausted and dies, and before your water-skin bursts, Paradise will become obligatory for you." Imam Abu Bakr (may Allah have mercy on him) says that I do not know of Abu Ishaq hearing from Kadeer.
