وَٱلَّذِينَ كَفَرُوٓا۟ أَعْمَٰلُهُمْ كَسَرَابٍۭ بِقِيعَةٍۢ يَحْسَبُهُ ٱلظَّمْـَٔانُ مَآءً حَتَّىٰٓ إِذَا جَآءَهُۥ لَمْ يَجِدْهُ شَيْـًۭٔا وَوَجَدَ ٱللَّهَ عِندَهُۥ فَوَفَّىٰهُ حِسَابَهُۥ ۗ وَٱللَّهُ سَرِيعُ ٱلْحِسَابِ
As for those who disbelieve, their deeds are as a mirage in a desert. The thirsty one supposeth it to be water till he cometh unto it and findeth it naught, and findeth, in the place thereof, Allah Who payeth him his due; and Allah is swift at reckoning.
Surah An-Noor(24:39)
Sahih al-Bukhari
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: Hajjat-ul-Wada
Narrated Ibn `Abbas:
A woman from the tribe of Khath'am asked for the verdict of Allah's Messenger (ﷺ) (regarding something) during Hajjat-ul-Wada` while Al-Fadl bin `Abbas was the companion-rider behind Allah's Messenger (ﷺ). She asked, "Allah's ordained obligation (i.e. compulsory Hajj) enjoined on His slaves has become due on my old father who cannot sit firmly on the riding animal. Will it be sufficient if I perform the Hajj on his behalf?" He said, "Yes."
