It is reported in Bihar that Ali (A.S.) said to
                          a man from Bani Sa'eed: "Should I speak
                          to you about Fatima and I? She was my
                          spouse who was the most beloved to the
                          Prophet. Once, she carried water using a
                          water skin until it scarred her chest, she
                          ground (grain) using a hand mill until
                          blisters appeared on her hands, she spet
                          thefloor until her clothes became dusty
                          and lit the fire under the cooking pot until
                          her clothes became mud colored from the
                          smoke. Fatima was inflicted by great pain
                          as a result of this, so I said to her:
                          'Why don't you ask your father for a
                          servant to relieve you from these jobs?'"
                          When Fatima (A.S.) went to the Prophet
                          (P.B.U.H.) and asked him for a servant to
                          releave her from these jobs, the Prophet
                          said: "Fatima, I will give you that which is
                          better for you than a servant and the world
                          with everything in it. When you lay down
                          to sleep and after every prayer say:
                          ALLAHU AKBAR (ALLAH is the greatest)
                          34 times,
                          ALHAMDU LILLAH (All praise belongs to
                          ALLAH) 33 times,
                          and SUBHAN ALLAH (Glory to ALLAH) 33
                          times; then conclude that with LA ILAHA
                          ILLA ALLAH (There is no God but ALLAH).
                          Surely his is better for you than which you
                          wanted and the world and it's belongings."
                          Thus, Fatima adhered to this glorification
                          after every prayer; and it came to be
                          known as "Tasbeeh-E-Zahra."
                          The thawab of the tasbeeh is equivalent to
                          the thawab of 1000 rakats in sunnat
                          namaz.
