The adultery of the limbs

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "The two eyes commit fornication, the two feet commit fornication, and the private part commits fornication."
Ahmad and Abu Ya'la recorded it, and he (Abu Ya'la) added these words: "And the two hands commit fornication." Al-Bazzar and al-Tabarani also recorded it, and the chain of both is jayyid (good).

Sayyiduna Abu Musa (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Every eye commits fornication."
Al-Bazzar and al-Tabarani recorded it, and the narrators of both are thiqat (trustworthy).

Muhammad bin Mutarrif narrates: My grandfather told me that he heard Sayyiduna Alqamah (may Allah be pleased with him), a Companion of the Prophet (peace and blessings be upon him), say: The Prophet (peace and blessings be upon him) said: "The fornication of the two eyes is looking."
Al-Tabarani recorded it. I do not know the grandfather of Muhammad bin Mutarrif; the rest of its narrators are thiqat (trustworthy).

Sahl bin Abi Umamah narrates that he and his father visited Sayyiduna Anas bin Malik (may Allah be pleased with him). This was in the time of Umar bin Abd al-Aziz, when he was the governor. He led a short prayer, as if it were the prayer of a traveller or close to it. When he had ended it with the salam, he (my father) said: "May Allah Almighty have mercy on you; was this the obligatory prayer, or a voluntary prayer you offered?" He said: "It was the obligatory prayer, and it is the prayer of the Messenger of Allah; I have not fallen short in any of it, except for something I forgot. The Prophet (peace and blessings be upon him) said: 'Do not be harsh on yourselves, lest harshness be imposed on you. Some people were harsh on themselves, so Allah Almighty imposed harshness on them, and their remnants remain in the cloisters and monasteries. (Allah Almighty says:) And monasticism, which they innovated; We did not prescribe it for them.'" Then, when the next day came, the people said: "Shall we ride out, look around and take a lesson?" He said: "Yes." So they all rode out, and there was a deserted settlement whose people had perished and come to an end, and only ruins remained. The people said: "Do you recognize this place?" He said: "No one knows this place and its inhabitants better than I. These are the people of a land whom transgression and envy destroyed. Indeed, envy extinguishes the light of good deeds, and transgression confirms that or denies it. The eye commits fornication, and the palm, the foot, the hand and the tongue (commit fornication), and the private part confirms that or denies it."
Abu Ya'la recorded it, and its narrators are the narrators of the Sahih except Sa'id bin Abd al-Rahman bin Abi al-Amya', who is thiqah (trustworthy).

Imam al-Sha'bi narrates: (Allah Almighty says:) "If you are given this (the ruling or verdict you want), accept it; and if you are not given it (the ruling or verdict you want), then beware (of accepting it)." He mentioned the two sons of Suriya, when the Prophet (peace and blessings be upon him) came to them and said to them: "By the One who revealed the Torah to Sayyiduna Musa (peace be upon him), and who split the sea, and by the One who sent down manna and quails upon you, are you the most knowledgeable?" They both said: "Our people have attributed that to us." Then one of them said: "He is adjuring us by the like of this." The Prophet (peace and blessings be upon him) said: "Do you find that looking is fornication, embracing is fornication, and kissing is fornication?" After this the narrator mentioned the hadith as before.
Abu Ya'la recorded it.
It is mursal, and its narrators are thiqat (trustworthy).

Sayyiduna Wathilah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Sexual relations between women are fornication."
Al-Tabarani recorded it, and Abu Ya'la also recorded it with these words: The Prophet (peace and blessings be upon him) said: "Sexual relations among women are fornication." Its narrators are thiqat (trustworthy).
