Will the blind pilgrim who covers his companion's expenses receive a doubled reward?

What is spent in obedience to Allah, its reward is commensurate with the expenditure. In the Hadith: "Your reward is commensurate with your toil," and in another narration: "commensurate with your expenditure or your toil." This means that the reward and virtue in worship increase with the increase in toil and expenditure. And whatever the blind person spends on Hajj, his reward is commensurate with his expenditure.
