"O Messenger of Allah! My father is an old man who cannot perform Hajj or 'Umrah, nor can he travel." He said "Perform Hajj and 'Umrah on behalf of your father." (Using translation from Nasāʾī 2637)
أَنَّهُ قَالَ يَا رَسُولَ اللهِ إِنَّ أَبِي شَيْخٌ كَبِيرٌ لَا يُطِيقُ الْحَجَّ وَلَا الْعُمْرَةَ وَلَا الظَّعْنَ قَالَ حُجَّ عَنْ أَبِيكَ وَاعْتَمِرْ
