On The Pool Of Kawthar

Mohammad bin Ali bin Faz’l bin Tamam Al-Zayyat narrated from Mohammad bin Qassem, from Abbad bin Ya’qoub, from Musa bin Uthman, from Aamash, from Abu Is’haaq, from Hareth, and Saeed bin Qays, from Ali bin Abi Taleb, who said:

The Messenger of Allah said:

I will be at the Pool of Kawthar on the Day of Judgement and you, O Ali, will distribute the water.

Hasan will keep people away from the Pool; Husain will give the orders; Ali bin Husain will be the enforcer; Mohammad bin Ali will be the revealer; Jaafar bin Mohammad will be the driver;

Musa bin Jaafar will be counting the lovers and the resentful, and he will be the destroyer of the hypocrites; Ali bin Musa will beautify the believers; Mohammad bin Ali will award degrees to the inhabitants of Paradise;

Ali bin Mohammad will be the preacher of his Shia and he will marry them from HUR AL-EEN, "Pure maidens with big beautiful eyes" (56:22).

Hasan bin Ali will be the light of the inhabitants of Pradise. They will see with his light, and the Qaem  (12th Imam ) will be the intercessor who will ask Allah (s.w.t.) to allow them (the believers) to enter Paradise on the day Allah (s.w.t.) will accept only the interession of those with whom He is pleased.
