A number of our companions, from Ahmad Bin Muhammad Bin Isa, from Al Husayn Bin Saeed, from Fazalat Bin Ayoub, from Dawood Bin Farqad who said, ‘I heard Abu Abdullah asws saying that the companions of the Prophet saww said to Sa’ad Bin Ubada, ‘What is your view, if you were to find a man upon the belly of your wife, how would you deal with it?’ He said, ‘I would strike him with the sword’. He (the narrator) said, ‘Rasool-Allah saww came out, so he saww said: ‘What is (the matter), O Sa’ad?’ He said, ‘They are saying, if you were to find a man upon the belly of your woman, what would you have done with him?’ So I said, ‘I would strike him with the sword’. So he saww said: ‘O Sa’ad! And how (will you get) the four witnesses?’ So he said, ‘O Rasool-Allah saww ! After having seen with my own eyes, and Allah azwj Knows that he has done it?’ He saww said: ‘Yes, by Allah azwj ! (Even) after having seen with your eyes and Allah azwj Knowing that he has done it, because Allah azwj Mighty and Majestic has Made a Penalty ( Hadd ) for everything, and Made upon the one who exceeds the Penalty ( Hadd ), a Penalty ( Hadd )’.

A number of our companions, from Ahmad Bin Muhammad, from Ibn Mahboub, from Abu Ayoub Al Khazaz, from Al Halby, Abu Abdullah asws having said: ‘In the Book of Ali asws , he asws used to strike with the whip, and by half the whip, and part of it regarding the Penalties. And when they came with a boy and girl who had yet to mature, he asws would not invalidate a single Penalty ( Hadd ) from the Penalties of Allah azwj Mighty and Majestic’. It was said to him asws : ‘And how did he asws used to whip?’ He asws said: ‘He asws used to take the whip with his asws hands, from its middle or from its third, then strike with it upon the measurement of their respective ages, and he asws would not invalidate a single Penalty ( Hadd ) from the Penalties of Allah azwj Mighty and Majestic’.

Muhammad Bin Yahya narrated to me, and someone else, from Ahmad Bin Muhammad Bin Isa, from Al Husayn Bin Saeed, from Al Nazar Bin Suweyd, from Aasim Bin Humeyd, from Abu Baseer, Abu Abdullah asws has said: ‘The stoning is a bigger Penalty ( Hadd ) of Allah azwj and the whipping is the smaller Penalty ( Hadd ) of Allah azwj . So when the married man commits adultery, he would be stoned and not whipped’.
