It was because of this incident that Allah revealed this chapter to His Apostle assuring him; it is as He (Glory be to Him) said: "You have lost your son, but We have given you Fatima; although she is just one, Allah will make that one many." A survey of the world's population attests to this conclusion; for Fatima's descendants (who are also the Prophet's descendants) are spread around the globe as follows: Iraq-one million, Iran-three million, Egypt-five million, Morocco-five million, Algeria, Tunis, Libya, Jordan, Syria, Lebanon, Sudan, the Persian Gulf countries including Saudi Arabia, Yemen, India, Pakistan, Afghanistan, and Indonesia-approximately twenty million descendants of the Prophet of Islam.

An Islamic country in which descendants of Fatima az-Zahra do not live is hard to find. Their number is estimated to be thirty - five million; however, if precise and accurate statistics are taken, their number could be much higher. Included among the Prophet's descendants are kings, princes, ministers, scholars, writers, prominent characters, and geniuses. Some are honoured by their lineage, and others ignore it and give no importance to it.

Some follow Ahlul-Bayt, while others violate their doctrine. I have even heard of some descendants of Fatima (sa) who live in Indonesia, and are enemies of Ahlul-Bayt (as)! More amazing is the fact that some Muslims refuse to accept their lineage of Fatima az-Zahra’s (sa), and ‘Ali (as); rather they claim that such a lineage is forged, and unacceptable. These people ferociously fought this idea up to the point that they shed innocent blood to implement their ideas.

Hajjaj, Mansour Dawaniqi, Haroon Al-Rashid, and others are known advocates of this idea. It was mentioned in volume ten of Bihar that Amr Al-Shube said: "One night Hajjaj summoned me to his palace; this horrified me, so I performed ablution and wrote my will; then went to meet him. When 1 entered his room, I saw a sword, and a leather mat (usually used for executions).
