Hadith 10:875
Abu Bakr narrated to us, he said: Ma’n ibn ‘Isa narrated to us, from Ibn Abi Dhi’b, from al-Zuhri, who said regarding the one who has taken an oath of abstention (from his wife): If he is ill, or if he is traveling, or if she is menstruating, I bear witness to his return (to his wife).
