Husain bin ‘Awf told me: I said: “O Messenger of Allah, the command for Hajj has come but my father cannot perform Hajj unless he is tied to a saddle.” Some time passed, then he said: “Perform Hajj on behalf of your father.”  

قُلْتُ يَا رَسُولَ اللَّهِ إِنَّ أَبِي أَدْرَكَهُ الْحَجُّ وَلاَ يَسْتَطِيعُ أَنْ يَحُجَّ إِلاَّ مُعْتَرِضًا فَصَمَتَ سَاعَةً ثُمَّ قَالَ حُجَّ عَنْ أَبِيكَ  

Husain bin ‘Awf told me: I said: “O Messenger of Allah, the command for Hajj has come but my father cannot perform Hajj unless he is tied to a saddle.” Some time passed, then he said: “Perform Hajj on behalf of your father.” (Using translation from Ibn Mājah 2908)  

قُلْتُ يَا رَسُولَ اللهِ إِنَّ أَبِي أَدْرَكَهُ الْحَجُّ لَا يَسْتَطِيعُ أَنْ يَحُجَّ إِلَّا مُعْتَرِضًا قَالَ فَصَمَتَ سَاعَةً ثُمَّ قَالَ «حُجَّ عَنْ أَبِيكَ»
