he was riding behind the Messenger of Allah and a man came and said: "O Messenger of Allah! My mother is an old woman and she cannot sit firmly in the saddle. If I tie her I fear that I may kill her." The Messenger of Allah said: "Don't you think that if your mother owed a debt you would pay it off?" He said: "Yes." Her said: "Then perform Hajj on behalf of your mother."(Shih) (Using translation from Nasāʾī 2643)
يَا رَسُولَ اللَّهِ إِنَّ أَبِي أَوْ أُمِّي عَجُوزٌ كَبِيرٌ إِنْ أَنَا حَمَلْتُهَا لَمْ تَسْتَمْسِكْ وَإِنْ رَبَطْتُهَا خَشِيتُ أَنْ أَقْتُلَهَا قَالَ «أَرَأَيْتَ إِنْ كَانَ عَلَى أَبِيكَ أَوْ أُمِّكَ دَيْنٌ أَكُنْتَ تَقْضِيهِ؟» قَالَ نَعَمْ قَالَ «فَحُجَّ عَنْ أَبِيكَ أَوْ أُمِّكَ»
