Prophet (SallAllahu Alayhi Wa Sallam) said:
“He who makes the pilgrimage to the House (of Allah), avoiding indecent and immoral behavior, emerges from his sins like a newborn baby.”
He also said:
“If some one sets out from his home as a pilgrim or visitant (mu’tamir) and then die, he (or she) is granted the reward of a pilgrim or visitant till the Day of Resurrection.
Anyone who dies in either of the sanctuaries (Mecca or Madina) is not subject to review or reckoning, but is told to enter paradise.”
In addition, the Prophet (SallAllahu Alayhi Wa Sallam) said:
“Pilgrims and visitants are the emissaries and visitors of Allah, if they petition Him He gives what they ask, if they seek His forgiveness He forgives them, if they call on Him He answers, and if they seek intercession it is granted.”
