وعن ابن عمر رضي الله عنهما أن رسول الله صلى الله عليه وسلم قال‏:‏ بني الإسلام على خمس‏:‏ شهادة أن لا إله إلى الله وأن محمدًا رسول الله، وإقام الصلاة، وإيتاء الزكاة، وحج البيت، وصوم رمضان‏"‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏

Ibn 'Abbas (May Allah be pleased with them) reported

A woman came to the Messenger of Allah (ﷺ) and said, "Allah's obligation upon His slaves has become obligatory on my father in his old age. My father is very old and incapable of riding. May I perform Hajj on his behalf?" He (ﷺ) said, "Yes."[Al-Bukhari and Muslim].
