“Blessed the man that hath visited ‘Akká, and blessed he that hath visited the visitor of ‘Akká."

"The Apostle of God—may the blessings of God and His salutations be upon Him—is reported to have said: “Blessed the man that hath visited ‘Akká, and blessed he that hath visited the visitor of ‘Akká." ...

 The Prophet—may the blessings of God and His salutations be upon Him—is stated to have said: “In ‘Akká are works of supererogation and acts which are beneficial, which God vouchsafed specially unto whomsoever He pleaseth. And he that saith in ‘Akká: ‘Glorified be God, and praise be unto God, and there is none other God but God, and most great is God, and there is no power nor strength except in God, the Exalted, the Mighty,’ God will write down for him a thousand good deeds, and blot out from him a thousand evil deeds, and will uplift him a thousand grades in Paradise, and will forgive him his transgressions. And whoso saith in ‘Akká: ‘I beg forgiveness of God,’ God will forgive all his trespasses.”

"It is from the bounty of God that man is selected for the highest degree; and the differences which exist between men in regard to spiritual progress and heavenly perfections are also due to the choice of the Compassionate One. For faith, which is life eternal, is the sign of bounty, and not the result of justice. The flame of the fire of love, in this world of earth and water, comes through the power of attraction and not by effort and striving. Nevertheless, by effort and perseverance, knowledge, science and other perfections can be acquired; but only the light of the Divine Beauty can transport and move the spirits through the force of attraction. Therefore, it is said: “Many are called, but few are chosen.” 2
