[Pooya/Ali Commentary 108:1] When the Holy Prophet's son, Tahir, born to Khadijah al Kubra, died, Amr bin As and Hakam bin As taunted the Holy Prophet by calling him abtar-tail-less, whose progeny has been cut off. This surah was revealed to give glad tidings to the Holy Prophet that abundance of unbounded grace, wisdom and knowledge, mercy and goodness, spiritual power and insight, in highest degrees, and of progeny has been given to him. It is mentioned in Sahih Bukhari, Sahih Muslim, Musnad of Ahmad ibn Hambal and other books of renowned Sunni scholars that the Holy Prophet said: "Kawthar is a stream of super excellence, exclusively belonging to me. Only the righteous believers (among my followers) will be allowed to drink from it. Ali shall distribute the water from it to them. On the day of judgement I will see some of my companions driven, like cattle, away from Kawthar. It will be announced that they are those who, after my departure from the world, deviated from the true religion and introduced innovations (based upon conjecture) to corrupt the faith." From that day Ali was known and referred to by the companions as saqi al kawthar. Kawthar also means abundance of descendants. The countless descendants of the Imams of the Ah ul Bayt, in the progeny of Ali and Fatimah are known as sayyids. They are the descendants of the Holy Prophet. Aqa Mahdi Puya says: This chapter guarantees abundance in every type of growth and profit to the Holy Prophet. In gratitude of the grant of "abundance", the Holy Prophet and his Ahl ul Bayt demonstrated highest standard of devotion in prayers and in giving everything they had in the cause of Allah. The sacrifice of Imam Husayn, his grandson, has been described as dhibin azim in verse 107 of Saffat (see commentary 3. For their salat see commentary of Baqarah: 3, 43, 45; Ta Ha: 132. In some degree or other, according to the grade of their submission, all the believing men and women receive some portion from the "abundance" given to the Holy Prophet, therefore they are commanded to pray salat regularly and sacrifice whatever they have in the cause of Allah whenever necessary. Aqa Mahdi Puya says: Nahr, in verse 2, means sacrifice. It may also mean "raising of hands" in prayer whenever Allahu akbar is said. In verse 3 it is said that the enemies of the Holy Prophet (and his Ahl ul Bayt as explained in the commentary of Baqarah: 2 to 5, page 51) will be lost in oblivion. It is a divine prophesy.
