بسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ(سوره کوثر: 1)

The name of Surah Kauthar is derived from the first verse, and Kauthar means abundant good things.

According to several narrations from Shia and Sunni, As ibn Wael, the father of Amr As, who was one of the great polytheists of Mecca, after the sons of the Prophet passed away and he had no more sons, because of taunts and sarcasm, said the holy prophet is without posterity.

In order to comfort the Prophet's heart and to answer this inappropriate speech, God revealed Surah Kauthar and announced the failure of the enemies and the durability and survival of the Prophet's generation among Fatima AlZahra(pbuh) generation. This verse is about Hazrat Zahra, because the generation of the Prophet is from the children of Hazrat Zahra and this generation continues and does not disappear.
