The sanctity of the wives of the mujahidin

Amr bin Shurahbil bin Sa'id bin Sa'd bin Ubadah reports from his father, from his grandfather, that the Prophet (peace and blessings be upon him) said: "Sa'd is protectively jealous, I am more protectively jealous than him, and Allah Almighty is more protectively jealous than me." A man asked: "Over what is Allah Almighty jealous?" The Prophet (peace and blessings be upon him) said: "Over a mujahid who is striving in the way of Allah, and in whose absence (an attempt is made to do evil) with his wife."
Ahmad recorded it within a long hadith, which concerns the tafsir of Surah al-Nur. Its chain contains Abu Ma'shar Najih, who is da'if (weak).

Sayyiduna Anas (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "Beware regarding the women of the ghazis (that is, the mujahidin)."
Al-Bazzar recorded it. Its chain contains Sa'id bin Zarbi, who is da'if (weak).

It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him): The Prophet (peace and blessings be upon him) said: "Whoever sits on the bed of a woman whose husband is absent, Allah Almighty will set a serpent upon him on the Day of Resurrection."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat. Its chain contains Ibn Lahi'ah; his hadith is hasan (good), and there is weakness in him.

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) reported this as a marfu' hadith: The Prophet (peace and blessings be upon him) said: "The likeness of one who sits on the bed of a woman whose husband is absent is that of a man who will be bitten by one of the black serpents on the Day of Resurrection."
Al-Tabarani recorded it, and its narrators are thiqat (trustworthy).
