Hadith 8:2481
Abu Bakr narrated to us, he said: Abu al-Ahwas narrated to us, from Talq, who said: I was sitting with Sa’id ibn al-Musayyib when a man came to him and said: "My father performed much Jihad but did not perform Hajj, so should I perform Hajj on his behalf?" Sa’id said to him: "The Messenger of Allah (peace and blessings of Allah be upon him) granted a concession to a man to perform Hajj on behalf of his father. And is it anything but a debt?"
حدثنا أبو بكر قال حدثنا أبو الأحوص عن طلق قال كنت جالسا عند سعيد بن المسيب فأتاه رجل فقال إن أبي كان كثير الجهاد ولم يحج أفأحج عنه فقال له سعيد كان رسول الله صلى الله عليه وسلم رخص لرجل حج عن أبيه وهل هو إلا دين
