Narrated from his father who said: "Al-Hasan and Al-Husain wore their ring on their left hand."

This Hadith is Hasan Sahih.

(the clerk of Al-Mughira bin Shu`ba) Once Al-Mughira dictated to me in a letter addressed to Muawiya that the Prophet used to say after every compulsory prayer, "La ilaha illa l-lahu wahdahu la sharika lahu, lahu l-mulku wa lahu l-hamdu, wa huwa `ala kulli shay'in qadir. Allahumma la mani`a lima a`taita, wa la mu`tiya lima mana`ta, wa la yanfa`u dhal-jaddi minka l-jadd. [There is no Deity but Allah, Alone, no Partner to Him. His is the Kingdom and all praise, and Omnipotent is he. O Allah! Nobody can hold back what you gave, nobody can give what You held back, and no struggler's effort can benefit against You]." And Al-Hasan said, "Al-jadd' means prosperity [??]."

Ilyas ibn Dighfal said: I saw AbuNadrah kissing on the cheek of al-Hasan.

concerning the Verse: 'Do not prevent them' (2.232) Ma'qil bin Yasar told me that it was revealed in his connection. He said, "I married my sister to a man and he divorced her, and when her days of 'Idda (three menstrual periods) were over, the man came again and asked for her hand, but I said to him, 'I married her to you and made her your bed (your wife) and favored you with her, but you divorced her. Now you come to ask for her hand again? No, by Allah, she will never go back to you (again)!' That man was not a bad man and his wife wanted to go back to him. So Allah revealed this Verse: 'Do not prevent them.' (2.232) So I said, 'Now I will do it (let her go back to him), O Allah's Apostle."So he married her to him again.

The Messenger of Allah (saws) sacrificed a ram for both al-Hasan and al-Husayn each (Allah be pleased with them).

Anas said When the verse “You will never attain righteousness until you give freely of what you love" came down, Abu Talhah said Messenger of Allah (saws), I think our Lord asks us for our property. I call you as witness that I dedicate my land at Ariha ‘to Him’. The Messenger of Allah (saws) said to him Divide it among your nearest relatives. So he divided it among Hassan bin Thabit and Ubayy bin Ka’b.

Abu Dawud said I have been gold by an Ansari Muhammad bin ‘Abdallah that the name of Abu Talhah is Zaid bin Sahal bin al-Aswad bin Haram bin ‘Amar bin Zaid bin Manat bin ‘Adi bin ‘Amr bin Malik bin al-Najjar; and Hassan bin Tabit is son of al-Mundhir in al-Haram. Thus both of them (Abu Talhah and Hassan) have their common link in Haram who is the third great grandfather. Ubbay bin Ka’b is son of Qais bin ‘Atik bin Zaid bin Mu’awiyah bin ‘Amr bin Malik bin al-Najjar. Thus the common tie between Hassan, Abu Talhah and Ubbay is ‘Amr (bin Malik). The Ansari said between Ubbay and Abi Talhah there are six great grandfathers.

Sa'id ibn AbuSa'id al-Maqburi reported on the authority of his father that he saw AbuRafi' the freed slave of the Prophet (saws), passing by Hasan ibn Ali (Allah be pleased with them) when he was standing offering his prayer. He had tied the back knot of his hair. AbuRafi' untied it. Hasan turned to him with anger, AbuRafi' said to him: Concentrate on your prayer and do not be angry: I heard the Messenger of Allah (saws) say: This is the seat of the devil, referring to the back knot of the hair.

`Ali bin Abu Talib came out of the house of Allah's Apostle during his fatal illness. The people asked, "O Abu Hasan (i.e. `Ali)! How is the health of Allah's Apostle this morning?" `Ali replied, "He has recovered with the Grace of Allah." `Abbas bin `Abdul Muttalib held him by the hand and said to him, "In three days you, by Allah, will be ruled (by somebody else ), And by Allah, I feel that Allah's Apostle will die from this ailment of his, for I know how the faces of the offspring of `Abdul Muttalib look at the time of their death. So let us go to Allah's Apostle and ask him who will take over the Caliphate. If it is given to us we will know as to it, and if it is given to somebody else, we will inform him so that he may tell the new ruler to take care of us." `Ali said, "By Allah, if we asked Allah's Apostle for it (i.e. the Caliphate) and he denied it us, the people will never give it to us after that. And by Allah, I will not ask Allah's Apostle for it."

`Ali bin Abu Talib came out of the house of the Prophet during his fatal ailment. The people asked (`Ali), "O Abu Hasan! How is the health of Allah's Apostle this morning?" `Ali said, "This morning he is better, with the grace of Allah." Al-`Abbas held `Ali by the hand and said, "Don't you see him (about to die)? By Allah, within three days you will be the slave of the stick (i.e., under the command of another ruler). By Allah, I think that Allah's Apostle will die from his present ailment, for I know the signs of death on the faces of the offspring of `Abdul Muttalib. So let us go to Allah's Apostle to ask him who will take over the Caliphate. If the authority is given to us, we will know it, and if it is given to somebody else we will request him to recommend us to him. " `Ali said, "By Allah! If we ask Allah's Apostle for the rulership and he refuses, then the people will never give it to us. Besides, I will never ask Allah's Apostle for it." (See Hadith No 728, Vol 5)

My father said, "I saw `Amr bin Abi Hasan asking `Abdullah bin Zaid about the ablution of the Prophet. `Abdullah bin Zaid asked for an earthenware pot containing water and performed ablution in front of them. He poured water over his hands and washed them thrice. Then he put his (right) hand in the pot and rinsed his mouth and washed his nose by putting water in it and then blowing it out thrice with three handfuls of water Again he put his hand in the water and washed his face thrice. After that he put his hand in the pot and washed his forearms up to the elbows twice and then again put his hand in the water and passed wet hands over his head by bringing them to the front and then to the back and once more he put his hand in the pot and washed his feet (up to the ankles.)"

Narrated Wuhaib:

That he (the Prophet in narration 191 above) had passed his wet hands on the head once only.

I saw the Messenger of Allah (saws) uttering the call to prayer (Adhan) in the ear of al-Hasan ibn Ali when Fatimah gave birth to him.

Another chain with similar meaning.

And this Hadith is Hasan Gharib Sahih.
