Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Hisham ibn Salim who has said the following: “Abu ‘Abd Allah(as) said:.. At dawn Jibril descended with a dish of mashed meat and wheat from paradise and said, ‘O Muhammad, this is made for you by al-Hur al-‘In. You can eat it with Ali and his children; it is not proper that people other than you eat it.’ The Messenger of Allah, Ali, Fatimah, al-Hassan and al-Husayn ate it (the food that Jibril had brought from paradise) and it gave the Messenger of Allah the ability in matters of going to bed with his wives which was equal to that of forty men, thus he (the Messenger of Allah) could go to bed with all of his wives in one night if he so wanted.’”( Al-Kafi: H 10221, Ch. 190, h 41 ; Majlisi said: Sahih in Miraat ul Uqool 20/422)
We read in Al-Kafi
A number of our people have narrated from Ahmad ibn Muhammad from ibn Khalid from his father or others from Sa‘d ibn s; from al-Hassan ibn Jahm who has said the following: “I once saw Abu al-Hassan(as) had used dye. I said, ‘I pray to Allah to keep my soul in service for your cause, I can see you have used dyes.’ He (the Imam) said, ‘Yes, readiness is of the matters that increases chastity of women and women neglect chastity because of their husband’s neglect of readiness.’ He (the Imam) then said, ‘Will you be happy to see her without readiness?’ I replied, ‘No, it does not make me happy.’ He (the Imam) said, ‘In the same way it will not make her happy to see you without readiness.’ He (the Imam) then said, ‘It is of the moral behavior of the prophets to maintain cleanliness, use perfumes, shave the hairs and going to bed with one’s wife very often.’ He (the Imam) then said, ‘Sulayman ibn Dawud(as) had one thousand women in one palace of whom three hundred were publicly known and seven hundred of them were secretly married. The Messenger of Allah(saw), had the ability equal to forty men of going to bed with his wives, he(the Messenger of Allah) had nine wives and moved among them every night and day.’”[Al Kafi: H 10230, Ch. 190, h 50]
We read in a tradition with a SAHIH chain from Imam Baqir(as) in Shia book Hayat-ul-Qaloob:
Imam Baqir(as) said: Prophet Sulayman(as) had a fort, having 1000 rooms made by Jinns for him, and in every room one of his wife used to live. From these 300 were his wives and 700 were concubines. Allah gave him the sexual strength of 40 men. He used to daily visit all of his women and used fulfill their desires.(Majlisi declared chain as Sahih, Hayat-ul-Qaloob vol 1, p. 644) .
